Advanced imaging to assess coronary artery disease and atherosclerotic plaque burden

There are two primary types of cardiac CT scans used to evaluate heart health. While they use similar technology, they provide very different information and have different clinical applications, costs, and radiation exposures.

Quantifies calcified (hardened) plaque in coronary arteries. Result is an Agatston score (0-1000+).

Visualizes both calcified and soft plaque using IV contrast. Assesses stenosis (blockage) severity.

For asymptomatic individuals interested in cardiovascular risk assessment and prevention, CAC is the preferred first test. It’s affordable, low-radiation, and provides excellent risk stratification without the need for IV contrast.

Important: If you have active symptoms (chest pain, shortness of breath with exertion, palpitations), do not self-order imaging. Seek medical attention immediately.
