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.

The use of advanced AI software to assess CCTA images continues to gain more momentum.

An example of artificial intelligence automated coronary artery calcium scoring shown by Coreline at ACC23. The AI also identifies and color codes the anatomy so help show the reviewing radiologist or cardiac imager what and where things were calculated. #ACC #ACC23

Cardiologists, radiologists and surgeons share ‘landmark’ document on assessing prosthetic heart valves with CT

RSNA and several other industry societies have shared a new expert consensus document on the significant value of cardiac CT. Echo remains an effective first-line imaging option, the groups wrote, but CT can make a big impact as well. 

Dana Smetherman, MD, MPH, MBA, FACR, chief executive officer of the American College of Radiology, explains an American Medical Association (AMA) resolution ACR is supporting to expand low-dose CT lung cancer screenings and coronary calcium scoring.

AMA resolution backs expanded low-dose CT screenings for lung cancer, heart risk

Dana Smetherman, MD, CEO of the American College of Radiology, discusses the policy, which urges for more robust promotion of low-dose CT as a public health tool.

Former American College of Cardiology president Kim Allan Williams, Sr., MD, an ACC delegate to the American Medical Association House of Delegates, discusses an AMA resolution aimed at improving public awareness of low-dose CT lung cancer exams that can screen for coronary artery calcium at the same time. 

Ty Bode, senior director of strategy at GE Healthcare, explains the details of a new, economical cardiac CT scanner GE Healthcare launched at the American College of Cardiology (ACC) 2025 meeting. The Revolution Vibe is designed specifically for coronary CT angiography (CCTA), but at a lower price point than the traditional high-end, flagship scanner that have traditional performed CCTA work.
