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.

One-stop CT, MR imaging: Future in diabetic care?

Quantifying body fat and other clinical factors in obese patients with diabetes using CT or magnetic resonance (MR) may help physicians detect and manage comorbidities such as cardiovascular disease, according to a review published in the May issue of Diabetes Technology & Therapeutics. But is that enough to justify “one-stop shop” imaging?

A cardiac CT scan being performed at Duly Healthcare in suburban Chicago in the spring of 2022. This is one of the first outpatient cardiology clinics in the U.S. to implement a CCTA program for screening non-acute chest pain patients and for structural heart evaluations. This applies to CCTA, CTA, Cardiac CT, and CT angiography and coronary CT angiography.

Be Mindful of the Stark Law in CCTA Alliances

Numerous radiology groups are currently discussing arrangements whereby cardiologists and the radiologists would essentially split the responsibilities for reading coronary CT angiography (CCTA) studies. Most commonly, as proposed, the cardiologists would read and generate a signed interpretation report, but limited to the cardiac portion of the

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."
