Elizabeth M. Hecht, M.D., professor of radiology, Columbia University, New York, explains the latest advances to help visualize the difficult to image pancreas. She was a moderator of a session on pancreatic imaging advances at the 2019 Radiological Society of North America (RSNA) meeting.

She explained computed tomography is the front line imaging modality, followed by MRI for more detailed examination of the soft tissue details. MRI tissue elastography can also help to differentiate pancreatitis from pancreatic cancer. Hecht also said PET-CT and endoscopic ultrasound also play roles in pancreatic imaging. She said new software is helping automate measurements and artificial intelligence (AI) is in development to help improve pancreatic imaging and to find new radiomic markers that might be missed by the human eye to better detect disease or risk stratify patients.

Magnetic Resonance Imaging (MRI) | January 06, 2020

Karen Ordovas, M.D., MAS, professor of radiology and cardiology at the University of California San Francisco (UCFS) School of Medicine and a Society of Cardiac Magnetic Resonance (SCMR) board member, explains how cardiac MRI can help in women's heart disease and to better define complex congenital heart anatomy. She spoke at the 2019 Radiological Society of North America (RSNA) meeting. 

She specializes in cardiac and pulmonary imaging, and has particular expertise in using CT and MRI techniques in cardiovascular imaging and the differences of presentation in imaging between male and female cardiac patients. Ordovas is helping advance education around heart disease in women and bring great awareness of quality tools to diagnose heart disease and how heart MRI can help. She also is heavily involved in the use of heart MRIs for pregnant women, since there is no radiation,  and patients with congenital heart disease where detailed imaging of the complex anatomy is required.

The use of cardiac MRI in congenital heart disease is common in serial imaging of patients with Tetralogy of Fallot (TOF), one of the most common congenital heart diseases for which patients are referred for post-operative magnetic resonance (MR) imaging evaluation. In the past few decades, surgery has proved successful, but most patients require repeat imaging throughout their lives and MRI can offer more detailed soft tissue imaging without the use of radiation.

Stroke | January 03, 2020

Ajay Choudhri, M.D., chairman of radiology, Capital Health, Hopewell, N.J., explains his center's experience using an artificial intelligence (AI) application to help auto detect intracranial hemorrhage. There are several AI stroke auto detection apps now available with FDA clearance or in development that were shown at the Radiological Society Of North America (RSNA) 2019 meeting. These are being adopted by hospitals and multi-center radiology practices the U.S. to flag suspected cases of ischemic stroke or brain bleeds for immediate reads. 

MaxQ AI Accipio hemorrhagic stroke detection software. MaxQ.AIThe software also offers a second set of eyes for more difficult to detect cases. Quickly determining is a stroke is ischemic or hemorrhagic is critical to the path of treatment. If caught early enough, TPA can be injected into patients to clear clots causing an ischemic stroke, but can cause massive brain damage or death if injected into a patient with a brain bleed. At advanced neuro-interventional centers, quickly determining the type of stroke is needed to know if they need to revascularize a patient or manage a hemorrhage.

Orthopedic Imaging | January 03, 2020

This is a demo of the EOS orthopedic X-ray imaging system at the recent 2019 Radiological Society of North America (RSNA) meeting. The system allows for weight bearing exams. EOS Imaging System the first technology capable of providing full-body, 2-D and 3-D images of pediatric patients in a standing position at a low dose of radiation. The vendor said the scans are much lower dose than computed tomography (CT).

EOS captures bi-planar images with two perpendicular X-ray beams that travel vertically while scanning the patient from head to toe. In less than 20 seconds, the EOS exam produces simultaneous frontal and lateral, low dose images. The two resulting digital images are processed by EOS' proprietary sterEOS software to generate a 3-D model of the patient's spine and/or lower limbs. These detailed images with only 20 seconds of radiation were previously unachievable before EOS technology.

Advanced Visualization | December 30, 2019

This is a hologram of a fracture from a computed tomography (CT) scan displayed by the start up company Voxon at the 2019 Radiological Society Of North America (RSNA) meeting. The technology uses a half millimeter thick glass plate that pulses up and down very rapidly while projecting 4,000 images per second. It can display standard DICOM radiology files or STL files used for 3-D printing.

There were at least four vendors showing holographic screens to display advanced visualization 3-D renderings of anatomy from medical imaging. All four of these screens could be viewed in true 3-D using normal vision without the need for special glasses or a virtual reality visor.

The images in this example flickers because of the different frame rates of the system and the iPhone used to film it, but the actual images appears much more stable.

MRI Breast | December 26, 2019

Gillian Newstead, M.D., director of global breast imaging and former professor at the University of Chicago, explains a large breast MRI screening study presented at the 2019 Radiological Society of North America (RSNA) meeting. 

The DENSE Trial Study Group included 40,000 women from the Netherlands who underwent standard mammography. Of these, 8,061 women were identified as having dense breasts and were offered supplemental MRI screening, and about half took advantage of the additional screening. Dense breast tissue which can obscure cancer on conventional mammograms but not on MRI. The MRI cancer-detection rate among the women who actually underwent MRI screening was 16.5 per 1,000 screenings.

The use of supplemental magnetic resonance imaging (MRI) screening in women with extremely dense breast tissue and normal results on mammography resulted in the diagnosis of significantly fewer interval cancers than mammography alone during a two-year screening period. The results were published in the Nov.  28, 2019, issue of The New England Journal of Medicine and presented earlier at the European Congress of Radiology (ECR) 2019.

Computed Tomography (CT) | December 26, 2019

Kevin Little, Ph.D., assistant professor and medical physicist, Department of Radiology, at The Ohio State University, explains how hospitals can better manage their computed tomography (CT) imaging protocols across their fleet of CT scanners from various vendors. He moderated a session on this topic at the 2019 Radiological Society of North America (RSNA) meeting.

He stressed the importance of CT protocol management to an imaging practice and showed examples of tools that can be used to develop consistent protocols across multiple systems. Little said it is important to develop awareness of the Management of Acquisition Profiles (MAP) IHE profile and features that should be requested from CT scanner vendors.

CT protocols, which include all clinical and technical parameters for a given study, are the starting point for achieving high-quality images with reasonable radiation and contrast doses. An imaging practice that desires to follow the "as low as reasonably achievable” (ALARA) principle and produce high-quality images should have standardized protocols across their enterprise. Accreditation standards require a periodic review of all scanner protocols. However, variations among vendors, models, and clinical indications mean that managing and optimizing dozens of parameters for each protocol on every scanner in a health system is challenging. Even when variations between systems are limited, managing protocol names and parameters across multiple systems can be difficult. The purpose of this symposium is to identify tools and techniques that may be used to manage protocols across multiple systems and to provide a framework for protocol optimization.

Magnetic Resonance Imaging (MRI) | December 20, 2019

James Carr, M.D., chair of the Department of Radiology, Northwestern University, and incoming 2020 President of the Society of Cardiac Magnetic Resonance (SCMR), explains why MRI is an ideal cardiac imaging modality, at the 2019 Radiological Society of North America (RSNA) meeting.

Heart MRI offers advantages over computed tomography (CT) and echocardiography because of its excellent soft tissue delineation and its ability to offer information beyond anatomical imaging, such as perfusion, morphology and metabolism. MRI can be technically challenging and the exams requiring a long time, but recent advances have helped cur cardiac imaging times down significantly. Automation and artificial intelligence (AI) also is making post-processing and quantification mush faster, brining it closer to the time it takes to scan and post-process CT imaging.
 
Northwestern is was one of the early adopters of cardiovascular MRI. Carr said heart MRI was not common in regular clinical use until the past decade at some luminary centers. In 2005, Carr was given the opportunity to develop a clinical cardiac MRI program at Northwestern.
 
He said MRI scanners have improved, and now much faster than a decade ago. They are also more optimized for cardiac imaging. While heart MRI is well known in large hospital centers, Carr said it still needs to develop and expand to community hospitals and rural hospitals outside major population centers. 

Artificial intelligence is playing a significant role in cardiac MRI automation of speeding workflow and quantification. Carr said these technologies will become mainstream in the next few years. AI also will play an increasing role in risk prediction based on new image analysis algorithms in development.

Radiation Dose Management | December 19, 2019

Mahadevappa Mahesh, Ph.D., chief of medical physicist and professor of radiology and medical physics, Johns Hopkins University, Baltimore, treasurer of the American Association of Physicists in Medicine (AAPM),a board member of the American College of Radiology (ACR), presented a late-breaking study on how medical imaging radiation dose has started to drop over the past decade. He is the co-chair of the National Council on Radiation Protection and Measures Report (NCRP), and presented the most recent NCRP data analysis at the 2019 Radiological Society of North America (RSNA) meeting.

The new NCRP 184 report covers the period between 2006 and 2016, the period of the most current CMS data. It shows a decrease of about 20 percent in the radiation dose the U.S. population receives from medical imaging, compared to the NCRP 160 that covered the period of up to 2006.

Key findings of the study include:

   • CT dose dropped about 6 percent, despite a 20 percent increase CT scans since 2006;

   • Drop of more than 50 percent for nuclear imaging scans, mainly due to fewer procedures being performed;

   • A 15-20 percent decrease across X-ray imaging modalities.

Mahesh says this shows the impact of using "as low as reasonably achievable" (ALARA) principals, new dose guidelines outlined jointly by numerous medical societies, and dose reduction initiatives like Image Wisely, Image Gently, and the American College of Radiology (ACR) Dose Index Registry.

He said there was growing concern a decade ago when the last council report was published, which showed a steep increase in radiation dose. This was mainly due to a rapid increase in the use of computed tomography (CT) and other types of X-ray based and nuclear radiotracer medical imaging. This prompted the ACR to create the Image Wisely program and push for the use of more thoughtful imaging doses based on patient size, using the "as low as reasonably achievable” (ALARA) principle. While CT dose was lowered, he said the biggest decline over all was in nuclear imaging.

Treatment Planning | August 21, 2019

This is an example of the Mirada DLCExpert deep learning software that automatically identifies organs, segments and auto-contours them as the first step in creating radiation oncology treatment plans. This example of a segmented prostate computed tomography (CT) scan being used to plan radiotherapy was created without any human intervention. It was demonstrated at the American Association of Physicists in Medicine (AAPM) 2019 meeting. 

This example shows OAR Space hydrogel (outlined in blue) injected to create space between the prostate and the rectum to prevent damage to that radiation sensitive structure. The gel is hard to identify on the CT scan because it looks like part of the rectum or prostate. But the softwares AI has been trained to identify it when present.

The DLCExpert software was cleared by the FDA in July 2018 and was first shown at ASTRO 2018. It automatically identifies anatomical structures and contours them to save staff time. The files created by the software are vendor neutral and can be imported into any vendor’s treatment planning system. Read more about this software.

Treatment Planning | August 21, 2019

This is a lung cancer tumor radiotherapy treatment plan for the Accuray CyberKnife system demonstrated at the American Association of Physicists in Medicine (AAPM) 2019 meeting. The blue lines are the radiation beam lines that are shot from different positions to all intersect in the tumor to deliver the prescribed amount of radiation and prevent damage to surrounding healthy tissue. The beams also are planned around the critical structure organs near the target tumor to limit their dose. The organs are color coded to differentiate them on the treatment plan and to help with the estimated radiation dose each receives based on the plan. After the plan is optimized, it is fed into the radiotherapy treatment system computer to deliver the treatment once the patient is positioned on the treatment table exactly as they are in the CT scans used to create the plan.

Computed Tomography (CT) | August 21, 2019

This is a quick walk around of a mobile 32-slice computed tomography (CT) scanner used for surgery, brachytherapy and proton therapy on display by Mobius Imaging at the 2019 American Association Of Physicists in Medicine (AAPM) meeting. The system simply plugs into a standard wall outlet and all of the required hardware and software is built into the gantry. There is no need for an equipment closet, cabinet or server tower. The company said the CT system was created by some of the same developers who built the O-arm mobile CT system, but they said this CT scanner is much more compact.

 

Radiographic Fluoroscopy (RF) | August 09, 2019

Shimadzu displayed the FluoroSpeed X1 conventional radiographic fluoroscopy (RF) system at the Association for Medical Imaging Management (AHRA) 2019 meeting in July. The system was pending U.S. Food and Drug Administration (FDA) approval at AHRA, but received FDA 510(k) clearance in early August 2019.

The system features a 33-inch aperture, large enough to place a wheelchair inside. It can be rotated 90 degrees in either direction and the deck can be parked in any position, making it easier for patients to get on and off the 660-pound weight table. The FluoroSpeed X1 offers controls that are ergonomic for technologists, with duplicate controls on each side for either a left- or right-handed tech. The machine also has a large aperture to allow swallow studies.

The FluoroSpeed X1 comes equipped with a 17 x 17-inch dynamic digital X-ray detector (FPD) in the table bucky, allowing it to both be used for fluoroscopy as well as radiographic exams.

CT Angiography (CTA) | August 07, 2019

This is a quick walk around of the new Siemens Somatom Go.top cardiovascular edition compact computed tomography (CT) scanner on display at the Society Of Cardiovascular Computed Tomography (SCCT) 2019 meeting in July. It is aimed at cardiology office based imaging and was released this past spring at the American College of Cardiology (ACC) meeting.

The system has removable tablets on each side of the scanner where the tech can adjust the machine, review scout scans and trigger the scanner. The idea is to improve workflow and allow the tech to remain at the bedside longer to be with the patient, rather tucked away in a remote control room using an intercom.

The entire system is built into the gantry seen here, so there is no need for extra equipment in a closet, cabinet or server tower.

It comes in a 128 slice configuration with 4 cm of anatomical coverage per rotation.

It uses the Stellar detector and tin filtration to eliminate low energy photons and help lower dose. It can be programmed to aid workflow by automatically removing bone, create cured planar reconstructions, lung CAD and other post-processing features so more time can be spent on reading scans. The scanner also comes with a HeartFlow FFR-CT starter pack.

Artificial Intelligence | July 03, 2019

Sudhen Desai, M.D., FSIR, interventional radiologist at Texas Children's Hospital, editor of IR Quarterly for the Society of Interventional Radiology (SIR) and on the Board of Directors for the Society of Physician Entrepreneurs, explained how artificial intelligence (AI) can assist in pediatric imaging and the pitfalls of training AI systems. He spoke at the 2019 Radiology AIMed conference

Deep learning algorithms require large amounts of patient case data to train the systems to read medical images automatically without human intervention. However, in pediatrics, there are often much lower numbers of normal and abnormal scans that can be used compared to vast amounts of adult exams available. This makes it difficult to train systems, so AI developers are coming up with innovative new ways to train their software. Compounding issues with training pediatric imaging AI is that the normal ranges change very quickly for young children due to their rapid development. He explained what is normal for a 2-year-old may not be normal for a 5-year-old.

Desai and other pediatric physicians who spoke at the conference said AI could have a big impact on pediatric imaging where there are not enough specialists for the increasing image volumes.

Lawrence Tanenbaum, M.D., Radnet vice president and chief technology officer, discusses some of the artificial intelligence (AI) products in radiology that are now commercially available and how AI developments will impact PET, MRI and CT imaging. He spoke at the 2019 Radiology AI-Med conference.

He said AI is helping medical imaging in the following areas:
   • Identify urgent findings and flagging these on the top of worklists.
   • Computer aided detection capabilities that go beyond the traditional to improve efficiency, boost diagnosis and highlight unexpected findings. 
   • Improving diagnostic image reconstruction
   • Tools to enhance the speed, resolution, radiation dose and overall quality of advanced imaging.

Radiation Therapy | May 21, 2019

This is a walk through of the ViewRay MRIdian MRI-guided radiotherapy system installed at Henry Ford Medical Center — Cottage. The system has been in service for about two years. The walk through shows the entry way into the vault and the warnings about entering an MRI environment. Anyone who enters the treatment room must undergo a metal detector scan first to make sure all ferrous metal is removed.

Magnetic Resonance Imaging (MRI) | May 21, 2019

This is a quick look inside the magnetic resonance imaging (MRI) neuro-interventional suite at Henry Ford Hospital in Detriot, Mich. This neuro-procedure room connects through a door to a traditional operating room and the patient can be transferred using a trolley cot system to move between the two rooms. The MRI is a Philips 1.5T Achieva and the MRI suite includes MRI-safe surgical instruments, furniture and anesthesia system.

Digital Radiography (DR) | May 20, 2019

This is a quick walk-around video showing the Siemens Healthineers Multix Impact digital radiography (DR) room X-ray system at RSNA 2018. The system offers an intuitive operating system to help improve productivity. The in-room touch user interface on the tube allows the technologist to remain at the patient’s side. And when unable to be at the patient’s side, the technologist is able to monitor and optimize positioning from the control room via the system’s patient positioning camera, potentially reducing repeat imaging and unnecessary patient dose. Lights at the top of the X-ray system automatically indicate it the patient anatomy is aligned properly with the exam type the technologist chose for optimal imaging to reduce the need for retakes. 

The Multix Impact also offers an intuitive user interface and graphical organ program selection. The positioning guide display on both the in-room touch user interface and the workstation supports precise, consistent patient positioning. Advanced motorization and tracking reduce the physical exertion of technologists and help prevent repetitive stress injuries.

The FDA cleared the system In January 2019. 

Advanced Visualization | May 16, 2019

This is an example of how virtual reality is being used in neuro-radiology to better evaluate patients using advanced imaging. This dataset shows a patient's brain MRI with fused tractography imaging for pre-operative planning. This was part of a 2018 Radiological Society of North America (RSNA) hands-on session by Vinodh Kumar, M.D., and Komal Shah, M.D., associate professors of radiology at MD Anderson Cancer Center.
