A safer way to diagnose coronary artery disease?

Cardiac CT angiography (CCTA), a noninvasive test to check for clogged heart arteries, is now considered a first-line test for people with suspected heart disease. This test uses a CT scanner, which takes multiple, rapid x-rays that are merged together to create a detailed, three-dimensional view of the heart’s arteries. CCTA appears to be just as effective as traditional angiography for detecting and preventing heart attacks, strokes, and death from heart disease, but with fewer procedure-related risks.
