Coronary CTA Scan

What is a Coronary CTA Scan?

A Coronary CTA scan is a new, exciting, and revolutionary technique that offers a rapid non-invasive evaluation of the heart and coronary arteries. . With our new 64 Slice CT Scanner, we can image the heart and coronary arteries with great anatomic detail. The information captured during the study with the use of a contrast medium is able to identify the coronary arteries and if present plaque in their walls with the creation of 3-D images on a computer screen. Coronary CTA can provide your physician a quick evaluation of stenosis and plaque with a high degree of accuracy. In addition, patients with stents and bypass grafts can also be easily assessed.

How long will it take?

Our new 64 Slice CT Scanner will asses your heart for coronary arteries for in just a few minutes. Please arrive 15 minutes prior to your appointment time.

How should you prepare?

You will be asked the following questions when scheduling an appointment: If you answer yes to any of them, you will be advised that you need to be pre-medicated prior to this contrast examination. The pre-medication instructions will be faxed to your referring physician.

If you answer yes to this question, you will be asked if you are insulin dependant, or take any form of metformin:
glucophage, glucovance, glyburide, glipizide, advandamet.

You will then be given instructions specific for a diabetic patient

If your heart rate is not lower than 65 beats per minute you may be given special instructions by your physician that may require pre-medication..

A recent Bun/Creatinine blood test is required for diabetic patients, or patients over 65 years of age.

How is a Coronary CTA different from other heart tests?

One of the more common heart tests is called cardiac catherteization. This test is more invasive and requires a longer patient recovery time. During this exam a catheter is typically inserted into a blood vessel in the upper thigh and then manuvered up to the coronary arteries. Then there is a contrast dye injected into the catheter to highlight the arteries. Coronary CTA on the other hand has the ability to also rule out significant narrowing of the major coronary arteries and can non-invasively detects soft plaque or fatty matter that could lead to future problems without lifestyle change or medical treatment.
