Frequently Asked Questions
Why is This Exam Done?
Your doctor has recommended you for coronary computed tomography angiography (CTA). A CT scanner uses a combination of a high-tech X-ray scanner and sophisticated computer analysis to provide detailed, 3D images of your moving heart and major blood vessels. CTA is used to examine the health of blood vessels in your body. It can be used to identify weakened sections of arteries or veins and to visualize blood flow, as well as to detect fatty or calcium deposits (plaques) in the coronary arteries. CT angiography provides your physicians with more-precise images of your blood vessels.
What Will Happen During the Exam?
- While positioning you on an exam table, the technologist will explain your procedure and answer any questions you may have.
- IV contrast will be used and injected through an IV placed in your arm.
- During the injection, you may experience a warm sensation all over your body and a metal taste in your mouth. This is normal.
- If you experience any itching, sneezing, nasal congestion, scratchy throat or swelling of your face, please notify the technologist immediately.
- You will be asked to lie flat on your back.
- The exam table will slide into the scanner, only covering the part of your body which is being studied. The scanner is open at the back and the front, allowing you to see out.
- The technologist will always be able to see and hear you during your exam.
- You may be asked to hold your breath for a short time while the scanner takes a series of pictures. The time it takes to actually acquire images is very brief.
- The images will be reviewed, and if necessary, some may be repeated.
- Even though the scan is about 10 to 15 minutes please allow for an hour prior to your exam to prep and monitor your heart rate.
