Computed Tomography

Cardiac computed tomography (CT) has become a primary cardiovascular imaging modality in the past 20 years, and was recommended as a 1A recommendation in the 2021 chest pain assessment guidelines. CT calcium scoring has became a primary risk assessment for coronary artery disease and whether patients should be on statins. Coronary CT angiography (CCTA) is used to for anatomical assessment of the arteries for plaque burden and to identify areas of blockage that may cause ischemia and heart attacks. Additional use of contrast CT perfusion or fractional flow reserve CT (FFR-CT) can offer physiological information on the function of the heart. CT plays a primary role in structural heart assessments for heart valves, repair of congenital defects and left atrial appendage occlusion (LAAO) for both pre-procedure planning and procedural guidance.

FDA grants AI software for imaging-based heart assessments its breakthrough device designation

The new software was also added to the FDA's Tap Pilot program, an honor reserved for “high-quality, safe, effective and innovative medical devices."

Kate Hanneman, MD, University Of Toronto, explains why vendors and hospitals are increasingly discussing lowing their carbon footprint by starting with radiology. 

What does radiology have to do with climate change?

Kate Hanneman, MD, explains why many vendors and hospitals want to lower radiology's impact on the environment. "Taking steps to reduce the carbon footprint in healthcare isn’t just an opportunity," she said. "It’s also a responsibility."

Philips launches new AI-enabled CT scanner aimed at cardiology at ECR 2024

Philips introduced a new CT system at ECR aimed at the rapidly growing cardiac CT market, incorporating numerous AI features to optimize workflow and image quality.

Nauman Mushtaq, MD, Northwestern Medicine, explains the value of CT coronary calcium scoring for patients and for the cardiology business model.

The many benefits of using low-cost CT coronary calcium scoring to screen patients

CT calcium scoring provides valuable evaluations of intermediate-risk patients in addition to making good business sense for hospitals. Nauman Mushtaq, MD, an interventional cardiologist with Northwestern, shared his own experience with this technology. 

Joseph Swicklik, RT, Mayo Clinic, demonstrates how to use magic to calm pediatric patients during imaging exams.

Using 'magic' to calm pediatric patients during imaging exams

Joseph Swicklik, RT(R)(CT), Mayo Clinic, says magic tricks can help calm pediatric patients to overcome anxiety and make medical imaging exams run much smoother.

Cleerly’s AI software for noninvasive FFR estimates receives a Category 1 CPT code

The company officially launched its Cleerly ISCHEMIA software for delivering noninvasive evaluations of CCTA exams in early 2024. This update provides a closer look at the software from a billing perspective. 

Examples of photon-counting coronary angiography showing how clarity improves as the thickness of the image is reduced. Top: 60-year-old female, with noncalcified plaque (arrowheads) and coronary stenosis (inset images). The reduced section thickness did not affect assessment in this patient. Bottom: 56-year-old female with calcified plaque (arrowheads) and coronary stenosis. The reduced section thickness leads to less calcium blooming and therefore a less severe percentage of stenosis.

Coronary artery disease classification improved with photon-counting CT

After a photon-counting CT, 54% of patients had their coronary artery disease classification downgraded.

Examples of the messages the Nanox AI algorithms display for incidental findings of spinal compression fractures and detection of coronary calcium. Both can help physicians better understand risk factors or need for therapy in patients through these types of opportunistic screenings on scans being performed for other reasons.

Routine chest CT often reveals patients at risk for cardiovascular disease, presenting radiology with ‘untapped’ potential

Rads only reported this incidental finding in about 31% to 44% of cases, experts detailed in the Journal of the American College of Radiology.
