CT coronary angiography (CCTA) uses a contrast-enhanced CT scan to produce detailed three-dimensional images of the coronary arteries, including both calcified and non-calcified (soft) plaque. Unlike the calcium score, which detects only calcified disease, CCTA shows the full picture of atherosclerotic buildup and can identify narrowings that may not yet be producing symptoms. It is the closest non-invasive equivalent to traditional catheter-based angiography.
CCTA is included in Longevity Tier 2 and above, where it is clinically indicated based on your age, risk profile, and (often) your CAC score. The scan requires a short IV contrast injection and medications to steady the heart rate for image quality. Findings are interpreted by a radiologist and reviewed by your longevity physician, and may inform referrals to cardiology where further investigation is warranted.
