Exam explanation

CT Angiogram (CTA) is a type of CT scan that specifically focuses on the arteries/arterial system in various parts of the body. It is used to provide detailed images of the circulatory system. CT Angiography is a non-invasive alternative to traditional angiography which involves inserting a catheter into the femoral artery.

Exam Preparation

Tell your physician or the technologist if there is any possibility that you are pregnant or if you have a history of allergies. Prior to the exam, a technologist may speak with you on the phone to obtain necessary medical information and discuss instructions to be followed the day of the exam.

During the Exam

To highlight the blood vessels, a contrast agent will be administered in the form of an injection. You will lay face up on a table, and it will move into the large donut shaped scanner. While inside the scanner, you will be able to see your outside surroundings. The technologist will talk with you from the control room where they can see you at all times. Periodically, you will be asked to hold your breath for a short period, not swallow, etc. This exam typically takes about 20 minutes.

CT Venogram

A CT Venogram (CTV) is similar to a CT Angiogram, but it focuses on the veins/venous circulatory system instead of the arteries.
