VIDEO: Example of PET-CT Artificial Intelligence Driven Image Reconstruction

PET-CT | December 04, 2020

This is an example of Canon's Advanced intelligent Clear-IQ Engine (AiCE) AI-driven image reconstruction software that is now being used to improve image quality on the Canon Celesteion Prime PET/CT nuclear imaging system. The deep learning is used to enhance the iterative reconstruction used to reduce noise and sharped high contrast resolution on positron emission tomography (PET) images from the digital PET detector used on the system. 

This example is a whole-body FGD PET scan of a patient with a large BMI with lung cancer.

The Cartesion Prime PET/CT is the industry’s only air-cooled digital PET/CT, provides variable bed time (vBT) acquisition as a standard feature. This and the new FDA 510(k)-pending AiCE technology were highlighted at the 2020 Radiological Society of North America (RSNA) virtual meeting.

Kirti Magudia, M.D., Ph.D., an abdominal imaging and ultrasound fellow at the University of California San Francisco, explains how an automated deep learning analysis of abdominal computed tomography (CT) images can produce a more precise measurement of body composition and better predicts major cardiovascular events, such as heart attack and stroke, better than overall weight or body mass index (BMI). This was according to a study she presented at the 2020 Radiological Society of North America (RSNA) virtual meeting.

Unlike BMI, which is based on height and weight, a single axial CT slice of the abdomen visualizes the volume of subcutaneous fat area, visceral fat area and skeletal muscle area. However, manually measuring these individual areas is time intensive and costly. A multidisciplinary team of researchers, including radiologists, a data scientist and biostatistician, developed a fully automated artificial intelligence (AI) method to determine body composition metrics from abdominal CT images.

Statistical analysis demonstrated that visceral fat area was independently associated with future heart attack and stroke. BMI was not associated with heart attack or stroke.

Radiation Therapy | November 15, 2020

Bruce Bauer, Ph.D., CEO of TAE Life Sciences. The company is developing boron neutron capture therapy (BNCT) as a new radiation therapy for cancer. A patient is first infused with a non-toxic boron-10 compound, which selectively accumulates in tumor tissue. A neutron beam is then focused on the tumor and the neutrons are captured by the boron and causes emission of alpha radiation particles within the tumor. Alpha particles have a a very short range, so this helps spare surrounding healthy tissue from radiation damage. 

Historically, BNCT clinical studies have been carried out using boronophenylalanine (BPA) and neutrons derived from the core of a nuclear reactor. While the clinical outcomes have been encouraging, the availability of better boron-10 compounds and access to a neutron source posed a significant barrier to clinical research and adoption of BNCT as a practical cancer therapy.

There is now a renaissance in BNCT with the availability of new accelerator-based neutrons sources and novel synthesis of boron-10 target drugs, allowing clinical research to expand with the goal to have BNCT available as a new treatment option for patients.

The secondary radiation reaction from BNCT, with cellular-level precision, spares more healthy tissues and can potentially treat cancers that otherwise have few treatment options.

The system requires a neutron accelerator, but this is smaller than a proton system and operates at much lower energy, so the shielding requirement is much lower, cutting construction costs.

Artificial Intelligence | November 11, 2020

Artificial Intelligence (AI) is becoming more common place in radiology practices, and emerging technologies are providing radiologists with sophisticated detection software to aid their reading and provide support for a busy workflow. With the progression of AI technology, vendors must look not only at what AI can do for the radiologist, but how the radiologist and the technician interact with that technology –  the goal should be increasing accuracy while also positively improving workflow. GE Healthcare is working to improve radiology AI workflow in its Centricity Universal Viewer.

Three key opinion leaders offers their views on what is needed to make AI more valauble and accessible to radiologists. These include:

   • Amy Patel, M.D., breast radiologist, medical director, Liberty Hospital Women's Imaging, assistant professor of radiology, University of Missouri-Kansas City.

   • Prof. Dr. Thomas Frauenfelder, M.D., vice chairman and professor of thoracic radiology, Institute for Diagnostic and Interventional Radiology, University of Zurich.

MRI Breast | October 14, 2020

Professor Christiane Kuhl, M.D., director of radiology, University Hospital Aachen, Germany, explains how breast magnetic resonance imaging (MRI) can be used to clearly identify breast cancers in women with dense breast tissue. In women with dense breasts, it can be very difficult to detect many cancers on standard mammograms because the cancers and dense tissue both appear white. MRI can help clearly define tumors and identify which nodules are cancer and which are benign, which can help greatly reduce the need for biopsies.

Kuhl is an expert in breast imaging and breast MRI. She helped develop an a shortened MRI protocol that allows breast MR images to be created in 3 minutes or less, rather than standard protocols that can take up to 30 minutes. In the interview she shows patient case examples of standard mammograms and the MRI supplemental imaging for the same patient to show the hidden tumors. 

She also explains the differences between standard 2-d mammography, the current standard of care, and the newer 3-D mammogram tomosythnesis technology, breast ultrasound and breast MRI technologies.

Breast Density | October 13, 2020

Professor Christiane Kuhl, M.D., director of radiology, University Hospital Aachen, Germany, explains what it means to have dense breasts and how density can hide cancers in mammograms. She offers an explanation describing dense breast tissue and that this occurs in about half of women. Density is itself a risk factor for breast cancer and the fact that dense tissue hides cancers on mammography means that supplemental imaging is needed to accurately diagnose these patients and avoid false positives, or needless tissue biopsies. Breast ultrasound and breast magnetic resonance imaging (MRI) can be used to see through dense tissue to better identify cancers and avoid the need for many biopsies.

Cardiac Imaging | August 12, 2020

Advanced visualization company Medis recently purchased Advanced Medical Imaging Development S.r.l. (AMID), which developed software to automatically track and measure strain in echocardiograms. That technology is now being adapted for strain imaging in CT and MRI. Using this imaging data, the software also can noninvasively derive pressure gradient loops and curves, similar to using invasive pulmonary arterial (PA) hemodynamic pressure catheters. This information is useful in monitoring critically ill patients on hemodynamic support and to monitor worsening severity of heart failure. 

The technology was discussed at the 2020 Society of Cardiovascular Computed Tomography (SCCT) virtual meeting. Examples of this technology are presented in this video.

VIDEO: Photon Counting Detectors Will be the Next Major Advance in Computed Tomography

Artificial Intelligence | August 12, 2020

Todd Villines, M.D., FACC, FAHA, MSCCT, explains how artificial intelligence (AI) might be used in the near future to automatically calculate CT calcium scoring and and radiomic feature assessments. This was a key take away during the Society of Cardiovascular Computed Tomography (SCCT) 2020 virtual meeting. 

Villines is the Julian Ruffin Beckwith Professor of Medicine, Division of Cardiovascular Medicine, University of Virginia, editor-in-chief of the Journal of Cardiovascular CT (JCCT),  and SCCT past-president.

AI is already commercially used to improve CT image reconstruction to increase the diagnostic quality of the images, especially from low-dose scans. AI is now being applied to automate time-consuming tasks in CT image reads, such as manually calculated calcium scores and automated contouring and quantification of anatomy and function of the heart.

Another area that is seeing a lot of research in in radiomics, where AI is being used to sift through thousands of CT scans to look for subtle imaging traits that may indicate the early development or worsening of disease. These subtle changes may not be evident to radiologists reading the scans, but AI software can identify similarities in patients as a trend and alert researchers to look at that specific trait as a potential imaging biomarker.

Computed Tomography (CT) | August 12, 2020

 

Todd Villines, M.D., FACC, FAHA, MSCCT, said photon counting CT detectors were a key new technology discussed at the Society of Cardiovascular Computed Tomography (SCCT) 2020 virtual meeting. He said the technology will likely replace conventional CT detectors in the next decade. Advantages of photon counting detectors include the ability to enhance image quality at the detector level with much clearer details than conventional CT technology.

These new detectors also can take a single scan and bin the various energies to reconstruct a range of mono-energtic scan renderings similar to dual-energy CT, but on a wider spectrum of kV levels. This spectral aspect of photon counting also allows material decomposition based on the chemical elements that make up various materials in the scan, including calcium and metals that make up stents, orthopedic implants and replacement heart valves. This enables easier, automated removal of metal blooming artifacts and the ability to clearly image inside calcified arteries.

CT Angiography (CTA) | August 11, 2020

Todd Villines, M.D., FACC, FAHA, MSCCT, explains how coronary plaque assessment will become a new risk assessment tool in cardiac CT. This was a key take away during the Society of Cardiovascular Computed Tomography (SCCT) 2020 virtual meeting in July. He is the Julian Ruffin Beckwith Professor of Medicine, Division of Cardiovascular Medicine, University of Virginia; editor-in-chief of the Journal of Cardiovascular CT (JCCT), and SCCT past-president. 

While basic plaque assessments have been available for several years on CT vendor and third-party advanced visualization software, it lacked automation standardization for what various values meant and clinical evidence it was relevant. However, several speakers in SCCT sessions said that is now changing, with more specific analysis being tested clinically and automation using artificial intelligence. 

Several key opinion leaders in cardiac CT said this new information and automation lwill likely lead to a revision of the current CAD-RADS scoring system used by radiologists and cardiologists when assessing the coronary event risk of patients. They are calling for the new CAD-RADS 2.0 to include a detailed plaque assessment.

Computed Tomography (CT) | August 11, 2020

Todd Villines, M.D., FACC, FAHA, MSCCT, explains some of the discussion on CT used for COVID-19 patients at the Society of Cardiovascular Computed Tomography (SCCT) 2020 virtual meeting in July. He is the Julian Ruffin Beckwith Professor of Medicine, Division of Cardiovascular Medicine, University of Virginia; editor-in-chief of the Journal of Cardiovascular CT (JCCT), and SCCT past-president. 

Early on in the COVID-19 pandemic in China, CT emerged as a key imaging modality and was found to be able to detect COVID ground glass lesions in the lungs sometimes prior to positive genetic PCR test results. Supporters of CT say the modality offers a way to get detailed anatomical and functional information using a short exam time and limits the exposure of staff to potential or known COVID-19 positive patients.

One area where cardiac CT is seeing a lot of increased his is for the evaluation of thrombus in the left atrial appendage (LAA). This is traditionally done using trans esophageal echo (TEE), but it required very close contact with the patient and direct exposure of staff to bodily fluids and potential viral shed from the patient exhaling with each breath.

Pooja Rao, Ph.D., co-founder of Qure.AI and head of research and development for the company, explains how the company's artificial intelligence (AI)-based auto detection software can be used to analyze radiology images. The vendor offers a U.S. Food and Drug Administration (FDA)-cleared emergency room computed tomography (CT) scan automated AI analysis tool to immediately identify areas of suspected intracranial bleeds and cranial fractures. The software offers immediate feedback for suspected areas of interest for the attending physician or stat read radiologist. This can enable faster diagnosis and treatment in neuro imaging cases, especially in meeting door to TPA time in patients with ischemic stroke.

Qure.AI also developed AI-based lung analysis software to detect a variety of abnormalities, which is working its way through FDA review. It is being used in some developing countries for mobile lung screening programs in remote areas. The vendor developed a self-contained unit for the AI to work without a PACS system or internet connection so there is immediate feedback on the image if someone may be positive. This greatly reduces the complexities of patient call backs in low-income areas that might be without out phones or web connectivity for followup. Rao explains how the technology is being implemented in this use case. AI might have its greatest impact on developing countries that do not have adequate healthcare resources of doctors.

qER detects and prioritizes scans containing Intracranial bleeds, cranial fractures, mass effect and midline shift. Image markings, bleed subtypes and labels are not available in the United States.

Coronavirus (COVID-19) | May 07, 2020

Interview with Geoffrey Rose, M.D., president of Sanger Heart and Vascular Institute with Atrium Health, in Charlotte, North Carolina, and a board member with the American Society of Echocardiography (ASE). He explains the impact if COVID-19 (SARS-CoV-2) on the cardiovascular service line and cardiac imaging. He said the virus has led to use of computed tomography (CT) not only as the frontline cardiovascular imaging modality to evaluate chest pain, but also for COVID-19 pneumonia imaging.

Rose said cardiac ultrasound is still used, but requires full personal protective equipment (PPE) and often abbreviated exams because of the close proximity of the sonographer and patient when performing echocardiograms. This has given rise to using dedicated point-of-care ultrasound (POCUS) systems to answer specific clinical questions quickly. Smart-phone based POCUS systems that use an app and a transducer plugged into the phone enable basic echo exams or evaluation of other parts of the anatomy quickly without the need to immediately sterilize an entire cart-based ultrasound system. These small systems also can be completely enclosed inside a transducer sheath and the phone and single transducer are much easier and faster to wipe down. He said the quality of the exams are not as good as fully enabled echocardiography systems, but it allows for quick assessments of ejection fractions and to triage if the patient needs more advanced imaging if the basic questions cannot be answered.

Since hospitals have shut down now for about two months, postponing normal checkups, and elective exams and procedures, Rose said doctors still need to visit with patients who have chronic conditions. Sanger and Atrium Heath modified its ambulatory electronic medical record (EMR) and is using video conferencing to perform virtual appointments now for the majority of these patients. He said telemedicine was not widely used before COVID-19 in his hospital system, but the pandemic will likely alter the care model for the future, with more telemedicine visits being used even after epidemic is over. He said use of POCUS and CT as frontline cardiac imaging modalities will also likely remain in place after the pandemic because of the efficiencies in care these technologies offer.

Stephen Bloom, M.D., FASNC, director of noninvasive cardiology (cardiac CT, nuclear cardiology and echocardiography) at Midwest Heart and Vascular Associates, Overland Park, Kansas. He is also a member of the American Society of Nuclear Cardiology (ASNC) Board of Directors, explains some of the issues involved and protocols used for cardiac imaging during the COVID-19 pandemic. His discussion includes computed tomography, cardiac ultrasound and nuclear imaging.

Right now, Bloom said it is difficult to test everybody and there is a shortage of masks, gowns and other personal protective equipment (PPE), and the imaging equipment needs to be sanitized each time it is used. He said it is just is not possible to image all the patients who need imaging right now. Hospitals also are trying to limit the number of healthy people people coming into hospitals for routine visits and tests to reduce their potential exposure to the novel coronavirus (COVID-19, SARS-CoV-2) and help containment efforts. 

"The tests should be done, very simply, if it changes the care of the patient. If it doesn't change the care of the patient, and it can be postponed, it should be postponed," Bloom explained. "I would say 80 percent of our cardiac imaging exams have stopped. It has been very dramatic."

Jeffrey Bundy, Ph.D., chief executive officer, United Imaging in the United States, explains the company's efforts to respond to the novel coronavirus (COVID-19) pandemic in the U.S., Europe and China. The company is putting its first semi-trailer based computed tomography (CT) system into service at a hospital in New York City.

United Imaging began working on new solutions for the U.S. after getting requests from its customers and seeing the needs in China and Europe. The company is collaborating with different vendors, including Sea Box and AMST to build both semi-truck trailer CT scanning rooms and those built into customized shipping containers. Other vendors are helping with infection control, ventilation, and easier cleaning/disinfection to help protect healthcare workers and patients.

The first transportable CT scanner was installed at the request of Maimonides Medical Center, the largest hospital in Brooklyn, New York, on the front lines of the current crisis. As the hospital scales its operations to meet the needs of an expected influx of coronavirus patients, doubling its capacity to 1,400 beds, United Imaging’s scanner will help expand its capacity for imaging studies to support diagnosis and treatment.

Hicham Skali, M.D., a staff cardiologist and member of the Non-invasive Cardiovascular Imaging Program at Brigham and Women’s Hospital (BWH), and at Brigham and Women’s / Massachusetts General Health Care Center at Foxborough, explains the new recommendations from the American Society of Nuclear Cardiology (ASNC) and from imagers in China and Singapore. The ASNC created a best practices document for nuclear cardiology laboratories during the novel coronavirus (COVID-19, SARS-CoV-2) pandemic. The suggestions in the guidelines can ally to any imaging modality, including computed tomography (CT), MRI and ultrasound. 

Skali elaborates on the following points in his discussion, which are specific recommendations in the ASNC and SNMMI COVID-19 guidance document:
   • Rescheduling non-urgent visits
   • Rescheduling elective surgeries and procedures
   • Using separate spaces for patients with known or suspected COVID-19 to prevent spread
   • Ensuring supplies are available
   • Promoting use of telehealth
   • Screen staff, patients and visitors before they enter the department
   • Minimize non-essential visitors into the department
   • Record symptoms at the start of the shift
   • Use personal protective equipment (PPE)for healthcare personnel
   • If available, use PPE for patients due to concern of asymptomatic transmission of COVID-19
   • Maintain strict hand hygiene
   • Maintain 6 feet distance in all patient/staff interactions when possible
   • Work remotely whenever feasible, especially with ready studies
   • Rotating staff schedules for on-site and off-site work
   • Use of rest only studies if possible
   • Use of half-time SPECT to speed exam times
   • Use of PET if available to speed exam times

Skali served as the moderator in for the ASNC on demand webinar COVID-19 Preparedness for Nuclear Cardiology Labs: Insights from the US, China and Singapore.

Regina Druz, M.D., FASNC, a member of the American Society of Nuclear Cardiology (ASNC) Board of Directors, chairwomen of the American College of Cardiology (ACC) Healthcare Innovation Section, and a cardiologist at Integrative Cardiology Center of Long Island, N.Y., explains the rapid expansion of telemedicine with the U.S. spread of novel coronavirus (COVID-19, SARS-CoV-2).

Druz spoke on the unprecedented expansion of telemedicine in the U.S. under COVID-19, seeing more use in the last two months, as opposed to the past two decades. The Centers for Medicare and Medicaid Services (CMS) previously only reimbursed for Telehealth in rural areas it determined had a shortage of doctors. However, in early March 2020, CMS dropped the geographic requirements and allowed Telehealth usage across th country as a way to mitigate person-to-person contact and keep vulnerable, older patients at home for routine check ups with doctors.

Druz has subspecialty certifications in nuclear cardiology, adult echocardiography and cardiac computed tomography (CT) and explains how Telehealth can be used to pre-screen patients and get patient sign off on procedures prior to coming in for an exam, helping speed the process in the hospital and limit personal contact.

Concerns about the rpaid spread of COVID-19 also has driven many radiology departments to convert to wider use of teleradiology to allow more radiologists to work from home and reduce person-to-person contact within the hospitals.

Teleradiology | March 26, 2020

John Kim, M.D., chairman, Department of Radiology, THR Presbyterian Plano, Texas, and chief technology officer at Texas Radiology Associates, explains the use of teleradiology during the novel coronavirus (COVID-19) outbreak in the U.S. The radiology group is part of Collaborative Imaging, a radiologist owned teleradiology alliance that enables radiologists to read studies using secure web links and an app.

The rapid spread of coronavirus has increased the value telemedicine solutions to help prevent person-to-person contact and take some clinicians out of the hospitals to work at home or office locations. This includes the use of teleradiology tools to read images and communicate with referring physicians.

Telemedicine allows for the continuity of care within healthcare facilities and patients and allows for safe distance without sacrificing the quality of care. It also saves patients from spreading germs to others, like while on public transportation or in the doctor’s waiting room, and to the healthcare providers who tend to them. Televisits also only last an average of 10 minutes, allowing physicians to assess patients more quickly and easily.

Jilan Liu, M.D., MHA, CEO for the HIMSS Greater China, explains how health information technology (HIT) was leveraged in China to help fight the outbreak of novel coronavirus (COVID-19, SARS-CoV-2). Her discussion includes use of artificial intelligence, telemedicine to reduce contact between people, using the electronic medical record to help record and track people COVID-19 patients had contact with, apps, internet hospitals, and how 5G networks helped speed up IT systems.

She was previously principal and consulting director of the Greater China Joint Commission International (JCI). As chief executive for HIMSS Greater China, Liu and her team made a significant breakthroughs with hospitals and the HIT industry in the greater China region to embrace international HIT standards, certification requirements and to rethink prudent approaches to IT investments and operations.

Ultrasound Imaging | March 20, 2020

Interview with Mike Stone, M.D., an emergency physician at Northwest Acute Care Specialists in Portland, Ore., director of point of care ultrasound education at Butterfly Network Inc., and and former chief of the division of emergency ultrasound at Brigham and Women's Hospital, Boston. He explains what clinicians look for in lung ultrasound to evaluate patients for plural wall thickening and areas of congestion inside the lung typical of pneumonia and seen in patients with novel coronavirus (COVID-19, also referred to clinically as SARS-COV-2). 

Small hand-held ultrasound systems may offer advantages over X-ray or computed tomography (CT), because the entire system can be contained inside a protective sheath, making it easier to disinfect the device rather than an entire imaging room. Point of care ultrasound (POCUS) systems also allow triage of patients in tents or other areas outside of the hospital where other imaging modalities are not available. 

Stone shares examples of COVID-19 ultrasound images from Butterfly Network POCUS system technology, which turns an iPhone into an FDA-cleared ultrasound device for multiple POCUS exam types. It is the first POCUS system reported to be used for triage and monitoring COVID-19 patients.
