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, a leader in AI-powered imaging evaluations, files for IPO

Heartflow, known for its AI-based CCTA evaluations, appears to be going public. The news follows years of momentum for the California-based company, including improved Medicare reimbursements for cardiac CT and a new Category I CPT code for its Plaque Analysis software.

New data highlight how Heartflow's AI software drives major shifts in heart care

One of the study's most significant findings was that patients managed using the advanced AI software saw LDL cholesterol drops of 18.7 mg/dL, with a 15% reduction in their risk of a cardiac event. Even patients with no calcified plaque saw significant changes in care management.

Cardiology still No. 2 in FDA-cleared clinical AI algorithms, trailing only radiology

Cardiology continues to be one of the most influential healthcare specialties when it comes to utilizing artificial intelligence.

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.
