Plaque Analysis and RoadMap Analysis, two artificial intelligence (AI)-enabled assessment products, may enhance clinical evaluation of coronary artery disease (CAD) on cardiac computed tomography angiography (CCTA).
The Food and Drug Administration (FDA) has granted 510(k) clearance to two emerging artificial intelligence (AI) tools that may improve the ability of clinicians to predict heart attack risk in asymptomatic patients.
HeartFlow’s Plaque Analysis, which offers quantitative assessment of plaque volume on cardiac computed tomography angiography (CCTA), has reportedly been studied in over 11,000 patients, according to the manufacturer.1 HeartFlow noted that earlier this month, the Centers for Medicare and Medicaid Services (CMS) started reimbursing plaque analysis as a separate outpatient service at hospitals.
HeartFlow said the recently FDA-cleared RoadMap™ Analysis facilitates quick detection of stenoses in major coronary arteries on CCTA. In a recently published study, researchers said the AI-powered algorithm had superior reproducibility in comparison to intra-reader reproducibility in quantifying coronary stenosis.2
John Farquhar, the president and chief executive officer of HeartFlow, said the combination of Plaque Analysis and RoadMap Analysis with the company’s coronary physiology assessment tool HeartFlow FFRCT “ … will enable further development of AI-powered risk scoring to better identify asymptomatic patients at risk of heart attack.”
“It is exciting to note the work HeartFlow is doing to bring forward the innovative technologies to help us advance our understanding and care for patients with coronary artery disease. Combining anatomy, physiology, and plaque morphology would be essential for personalized patient care,” noted Jagat Narula, M.D., Ph.D., the chief of cardiology at Mount Sinai Morningside Hospital.

March 21st 2025Photon-counting CT fat fraction evaluation offered a maximum sensitivity of 81 percent for detecting steatosis and had a 91 percent ICC agreement with MRI proton density fat fraction assessment, according to new prospective research.
AI-Initiated Recalls After Screening Mammography Demonstrate Higher PPV for Breast Cancer
March 18th 2025While recalls initiated by one of two reviewing radiologists after screening mammography were nearly 10 percent higher than recalls initiated by an AI software, the AI-initiated recalls had an 85 percent higher positive predictive value for breast cancer, according to a new study.
