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.

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

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.

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.

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.

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.

VIDEO: Office-based cardiac CT and FFR-CT offer a new business model

In a new video, Evans Pap­pas, MD, and Sujith Kalathiveetil, MD, both of Duly Health and Care in suburban Chicago, explain the shift toward office-based cardiac CT evaluations and the role of FFR-CT. 

New-look imaging technique could change the way we see blood vessels

The new method, still being tested with mouse models, could help clinicians see blood vessels with improved clarity.

CT a low-risk imaging alternative to invasive coronary angiography for suspected CAD

The new analysis focused on data from 16 different European countries.

Ron Blankstein, MD, professor of radiology, Harvard Medical School, explains the use of artificial intelligence to detect heart disease in non-cardiac CT exams.

Eleven medical societies have signed on to a consensus statement aimed at standardizing imaging for suspected cardiovascular infections.
