Q. How CT Coronary Angio is done?

As explained earlier CT Coronary Angio is a totally non-invasive (painless) procedure. You will be taken to the CT scan room, after routine ECG and blood tests to exclude kidney problems. You may lie flat on the CT table and an intravenous line will be inserted in to one of your arms veins. If you chest is hairy we need to shave over a little area of the chest, to fix the ECG leads. You will be given a tablet to control your heart rate, which will be prescribed by our cardiologist after taking your ECG or Echocardiography. You will be instructed to hold breathe during scan. Your scan is done by CT equipment along with ECG gating. During the scan non-ionic contrast medicine will be injected through the arm vein, which may give you a slight warm sensation.

Q. How long does it take for CT Coronary Angiogram?

The actual scan takes less than 5 seconds. But, you need to be prepared for the scan which takes 30 minutes to 1 hour. So, your stay in Star Imaging & Path Lab can range from 1-2 hours.

Q. Is there any risk in undergoing this investigation?

Like conventional angiogram CT Coronary angiogram also uses X-ray radiation. But, the levels of radiation used are minimal below any harmful levels. Further, the latest Optima 500 Slice Scanner at Star Imaging & Path Lab has unique prospective cardiac scan module which reduces the radiation exposure to less than 50% to 80% in comparison to other equipments.

Q. What all the other scans we can combine with CT Coronary Angiogram in addition?

CT Coronary Angiogram with CT Chest.

CT Coronary Angiogram with CT Abdomen.

CT Coronary Angiogram with Renal Angiogram.

Your doctor will tell you how to prepare for the cardiac CT scan. People usually are asked to avoid drinks that contain caffeine before the test. Normally, you're allowed to drink water, but you're asked not to eat for 4 hours before the scan.

If you take medicine for diabetes, talk with your doctor about whether you'll need to change how you take it on the day of your cardiac CT scan.

Tell your doctor whether you:

  • Are pregnant or may be pregnant. Even though cardiac CT uses a low radiation dose, you shouldn't have the scan if you're pregnant. The x rays may harm the fetus.
  • Have asthma or kidney problems or are allergic to any medicines, iodine, and/or shellfish. These problems may increase your chance of having an allergic reaction to the contrast dye that's sometimes used during cardiac CT.

A technician will ask you to remove your clothes above the waist and wear a hospital gown. You also will be asked to remove any jewelry from around your neck or chest.

Taking pictures of the heart can be hard because the heart is always beating (in motion). A slower heart rate will help produce better quality pictures.

If you don't have asthma, COPD (chronic obstructive pulmonary disease), or heart failure, your doctor may give you a medicine called a beta blocker to help slow your heart rate. The medicine will be given by mouth or injected into a vein.
