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.

Statin reduces risk for non-obstructive CAD patients but no significant risk reduction for aspirin

The results of a study published in Radiology: Cardiothoracic Imaging call into question the value of initiating aspirin therapy in certain instances.

Heartflow FFR-CT allows noninvasive assessment of a patient'c coronary arteries without the need for a diagnostic angiogram.

VIDEO: HeartFlow FFR-CT sees increased interest after inclusion in the 2021 Chest Pain Guidelines

HeartFlow’s non-invasive cardiac computed tomography derived fractional flow reserve (FFR-CT) technology enables FFR values for the entire coronary tree of a patient using just a CT scan. This can show the significance of any coronary plaque lesions and if a patient needs to be sent to the cath lab for revascularization, or if they can be treated medically.

Radiologists in Ukraine helping the war effort as Russia continues to attack

Many radiologists stepped up to do their part for the war effort by staying at their hospital posts and helping the wounded as they started coming in.

A figure from the 2022 CAD non-invasive imaging guidelines showing a comparison of computed tomography angiography (CTA) and a SPECT-CT vs. an invasive angiogram from the cath lab showing the same blockage in a coronary artery.

New multi-society recommendations highlight role of non-invasive imaging in evaluating coronary artery disease

A new, multi-society document, "Non-Invasive Imaging in Coronary Syndromes," focuses on how multiple imaging techniques can evaluate different aspects of coronary artery disease (CAD), all without the need for invasive angiograms.

Why cardiologists and radiologists are choosing cardiac CT over invasive angiography for suspected CAD

"A CT-first strategy allows physicians to provide relevant findings without the need for an invasive procedure," one radiologist explained. 

PHOTO GALLERY: Duly Health adopts outpatient cardiac CT as a standard of care

Duly Health and Care in suburban Chicago recently opened a new outpatient cardiac evaluation center equipped with a dedicated cardiac CT system, which will likely be a new business model that will be seen more in the coming years.

Leslee Shaw, PhD, and former presidents of both SCCT and ASNC discusses the role of CT and FFR-CT in the 2021 chest pain guidelines.

VIDEO: Cardiac CT now recommended as a front-line chest pain assessment tool

Leslee Shaw, PhD, director of the Blavatnik Family Women’s Health Research Institute at Mount Sinai Hospital in New York and former president of the Society of Cardiovascular Computed Tomography (SCCT) and the American Society of Nuclear Cardiology (ASNC), explains the role of cardiac computed tomography (CT) in the recent 2021 chest pain guidelines.
