Coronary CT Angiography (CCTA)


Coronary CT Angiography (CCTA) is a diagnostic procedure using computed tomography to scan the coronary arteries. It is a non-invasive technique that allows clear visualization of narrowed and clogged arteries that can cause heart attack and stroke. Coronary CCTA is not appropriate for everyone, and a referral from your physician is required for the scan.

Computed tomography is an excellent diagnostic tool. In a CT scan, the X-ray beam moves in a circle around your body. This allows many different views and provides much greater detail than a standard X-ray. The X-ray information is sent to a computer that displays it in two-dimensional or three-dimensional form on a screen.

CCTA is offered at both St. Joseph Medical Center and St. Elizabeth Hospital.
