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.

The AI provides visualization and quantification of the location and severity of anatomic narrowings. Right image, HeartFlow's Plaque Analysis AI algorithm automates assessment of coronary plaque characteristics and volume on CCTA exams to greatly reduce the time it takes to manually assess and quantify these features.

The solutions, Plaque Analysis and RoadMap Analysis, both use coronary CT angiography to provide clinicians with a noninvasive look at patients who present with coronary artery disease and face a heightened myocardial infarction risk.

Coronary CT Angiography (CCTA) has evolved into a much more helpful resource than interventional cardiologists may have originally believed. In fact, the Society of Cardiovascular Computed Tomography (SCCT) emphasized in a new expert consensus statement that CCTA provides specialists with an effective tool in the preparation and optimization of coronary procedures. The 2021 chest pain guidelines elevated CTA to a class 1A recommendation. Harold Litt , MD, explains the use of CCTA in the ED.

CT has been used for planning and procedural guidance in pulmonary vein isolation (PVI) for about 20 years. It shows the anatomy to the electrophysiologist. The EPs also can load the imaging into their EP mapping system. It also shows them the location of the esophagus and the phrenic nerve so they can avoid these during the procedures. #PVI #EPeeps

As the population of patients with adult congenital heart disease grows, they are presenting to adult cardiology clinics and being imaged with CT. Many also do not have access or cannot be imaged by MRI, said Renee Bullock-Palmer, MD.

New recommendations for cardiac CT in cardio-oncology imaging

The statement was written to fill gaps in recommendations from prior consensus statements and guidelines in regards to the use of CCT in cardio-oncology, including use of calcium scoring and ruling out coronary disease when cardiac function is impaired.

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."
