The preparation

  • The doctor will advise you not to eat and drink anything before the test for at least eight hours. Do not drink liquid with caffeine or any caffeine-related products at least 12 hours before the test as it will affect the imaging procedure giving rise to a blurring effect.
  • It is better to come with someone rather than alone as some patients may feel nauseous or exhausted after the CT coronary angiography procedure. Sometimes the drowsy effect can stay up 24 hours after the completion of the procedure.
  • In some special cases, a patient will need to get admitted to the hospital to undergo the process. The examiner will discharge him within the same day or the next day after the procedure.

  • Once you are in the clinic or hospital, you must sign a consent form.
  • Then it would be best if you changed into the hospital gown to undergo the procedure and had to remove any accessories, pieces of jewelry, glasses etc till above the waist.
  • The staff will check some of your vitals, like blood pressure or blood sugar, in case you have diabetes. Sometimes the doctor may ask you to undergo an electrocardiogram test. You may even require a certain blood test. Your health care provider will inform you about the required test once they assess your case.
  • Sometimes the examiner may inject certain medicine to slow the heart rate. This is called a beta blocker. This process will yield better imaging, and a more precise image. If you have any previous allergic reaction to this medicine or any other medicine, please inform the clinic to avoid any undesirable effects.
  • At last, your doctor will inject a mild sedative to help you make comfortable, although you will remain awake throughout the procedure.

The process

  • CT angiography test is a bit complex; the technician will first use an anaesthetic on your groin or arm to numb the section.
  • Then, the examiner will inject a dye or contrast agent through your arms by using an IV. The function of the dye is to help the technician to locate your blood vessels more clearly. Once the dye is injected, you may feel a burning sensation.
  • The examiner may attach the electrodes to your chest to monitor heart rate
  • Then he will slowly insert a sheath within the artery. You may feel a bit of pressure, but that is bearable
  • Then the examiner will slowly guide up a tube known as a catheter up to the artery in your heart 
  • While the scanning procedure starts, you will need to stay calm and still to retrieve a better image.
  • An intercom present in your room will enable you and your technician to communicate with each other from a separate room.
  • After Process
  • After your CT coronary angiogram, you are free to go back to your normal life. You may feel a bit dizzy due to the application of a sedative, so it is better not to drive back home alone. Drink lots of water to flush off the contrasting agent from your system
