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.

$Performing CT-derived fractional flow reserve (CT-FFR) before transcatheter aortic valve replacement (TAVR) improves the accuracy of coronary CT angiography (CCTA) and helps limit unneeded invasive coronary angiography (ICA), according to a new study published in JACC: Cardiovascular Interventions.

AI-based CAD assessments dramatically improve vascular surgery outcomes
PAD patients evaluated with HeartFlow's noninvasive FFR_CTAnalysis technology prior to surgery experienced much better outcomes, including a 63% lower risk of all-cause mortality after five years.
AI helps cardiologists track new drug's effect on inflammation
The combination of AI and CT helped Nehal Mehta, MD, and colleagues track the performance of a new drug designed to target coronary inflammation.
AI improves CT assessments, boosts care for real-world heart patients
Automated AI-generated measurements combined with annotated CT images can improve treatment planning and help referring physicians and patients better understand their disease, explained Sarah Jane Rinehart, MD, director of cardiac imaging with Charleston Area Medical Center.
AI predicts cardiovascular risk during CT scans—no invasive tests or contrast required
Two advanced algorithms—one for CAC scores and another for segmenting cardiac chamber volumes—outperformed radiologists when assessing low-dose chest CT scans.
CT procedure shown to reduce need for invasive cardiac testing
In a study, CT-FFR was shown to reduce the need for invasive tests to measure coronary artery blockage from 74.5% to 25.5%.

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.

Cardiac computed tomography (CCT) is an accurate, noninvasive imaging test that should be a first-line tool when treating patients with obstructive coronary artery disease (CAD), rather than cath lab angiography angiograms, according to new findings published in the New England Journal of Medicine.[1]

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.
