Coronary CT Angiography (CCTA)

Coronary CT Angiography (CCTA) uses a CT (Computed Tomography) scanner to examine blood flow through the small arteries that feed the heart. It is a non-invasive way to look for artery narrowing or blockage, and examine the walls of the arteries. Our technicians will place an IV with contrast material (dye) into a vein so blood flow can be seen more clearly. Your doctor may request this exam if you’ve experienced non-emergency (non-acute) chest pain, new or worsening symptoms after receiving a normal stress test result, or if results of a stress test were inconclusive.

Coronary CT Angiography scans are available at the following Advanced Radiology locations

CT Angiography scans are pain-free and usually take no more than 15 to 30 minutes to complete. If you are scheduled for a CT Angiography study, contrast media (a dye) will be injected to better visualize blood flow. You should fast—have no food—for 4 hours prior to the exam. You may have clear liquids up to 1 hour before your exam.
