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.

A medical professional trained to manage contrast reactions should be on-site at any imaging facilities doing contrast studies to maintain patient safety, according to a an updated statement from the American College of Radiology. The ACR has released the latest edition of the ACR Appropriateness Criteria, which includes 221 diagnostic imaging and interventional radiology topics with more than 1,050 clinical variants covering 2,900 clinical scenarios. #ACR #AUC #appropriateuse

Addressing contrast media shortage in the short, mid and long term

“We need to commit to changing the supply chain so that a single event in a faraway country does not put us in this predicament again," experts wrote in a new special report shared by Radiology.

CT-FFR before TAVR improves detection of coronary artery disease, limits invasive imaging exams

CT-FFR, which recently got a boost from the 2021 AHA/ACC chest pain guidelines, could play a key role for clinicians hoping to screen TAVR patients for coronary heart disease.

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."
