What is a cardiac CTA test?
Coronary CT angiography (CTA) is a noninvasive test that uses X-rays in the form of computed tomography to diagnose coronary artery disease. Coronary CTA provides high-resolution images of the blood vessels supplying the heart, allowing identification of narrowing or blockages caused by plaque.
How long does a cardiac CTA take?
As the heart beats, the contrast material outlines the vessels, valves and chambers and pictures are taken to identify blockages or narrowed areas in the coronary arteries. The average catheterization procedure lasts about 30 minutes, but the preparation and recovery time add several hours.

CT and CTA – What’s the Difference? Computed tomography (CT) scans take cross-sectional images of soft tissues or skeletal anatomy. Computed tomography angiography (CTA) takes the CT scan a step further by creating cross-sectional images of soft tissues, skeletal anatomy, and vascular structures.
Do you have to take your clothes off for a CT scan?
You will need to take off all or most of your clothes, depending on which area is studied. You may be able to wear your underwear for some scans. You will be given a gown to use during the test. During the test, you will lie on a table that is attached to the CT scanner, which is a large doughnut-shaped machine.
What is CTA procedure?

What is a CTA of the chest?

What is a non – contrast CT scan?
