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.

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.

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.

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.

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.

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.

Candice Johnstone, M.D., MPH, Medical College of Wisconsin explains the need for palliative radiotherapy and patient selection considerations at the American Society for Radiation Oncology (ASTRO) 2019 annual meeting. 

Despite improvements in the survival of some populations of cancer patients, some patients are not candidates for ablative therapy and need symptom relief. Cases will be used to highlight evidenced based approaches to palliative radiation therapy. A significant proportion of patients do not benefit from immunotherapy and need standard palliative radiation. The best palliative radiation utilizes the fewest number of fractions to achieve the desired effect, minimizes side effects of treatment and treatment related costs.
