Coronary CT Angiography - Los Angeles, CA

The same preps apply for thoracic aorta with coronary angiography, pulmonary vein mapping, cardiac anatomic structure studies and valve replacement planning imaging.

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 than either MRI or ultrasound technology. Our team of subspecialty imaging physicians is led by Daniel S. Berman, MD, chief of Cardiac Imaging and Nuclear Cardiology.

After your study, you may be contacted about our CT angiography research (ADVANCE) registry

Continue taking all of your current medications. Do not take Viagra^®, Cialis^® or Levitra^® for 48 hours before exam.
Fasting is not required for this exam, but drinking water is encouraged.

Leave all jewelry and valuables at home.
Though we do not anticipate any delays in your exam, please consider bringing a book, magazine or music player to help you pass the time while you are waiting.

After Arriving

A radiology nurse or technologist will ask you a few questions regarding your medical history.
Please tell the technologist, radiology nurse and/or physician of any allergies you may have before your exam, or if you are or might be pregnant.
To obtain best images of your heart, your heart rate must be at 60 beats per minute (bpm) or lower. If your heart rate is higher than 60 bpm, the nurse will give you a pill (a beta blocker) to lower your heart rate. It may take up to an hour for the pill to lower your heart rate to 60 bpm.
You will be asked to change into a hospital gown and a nurse or technologist will insert a small IV in your arm.

During Your Exam

While positioning you on an exam table, the technologist will explain your procedure and answer any questions you may have.
If contrast dye is being used, it will be injected through your IV.
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. In some cases, pillows or straps may be used to keep the area being examined from moving during the scan.
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.
This procedure usually takes approximately 15-30 minutes. Your total time commitment will be between two and three hours.

After Your Exam

You may resume your normal diet.
If you received an injection of contrast dye, you should drink six to eight glasses of water to flush it out of your system.
An imaging physician will examine your images and write a report of their findings. This report will be sent to your physician, usually within 24 hours. Some scans require more computer processing, and these may take longer to analyze.
Your physician will contact you with the results of your exam.
