CT Scan: What is it? A CT scan is an X-ray examination of a part of your body that produces computer-generated, cross-sectional images of your insides. It may require an intravenous injection of contrast medium into a vein, usually at your elbow or the back of your hand.

What You Must Tell Us Beforehand:

• If you have had an adverse reaction to a previous contrast injection or other drugs.
• If you have any renal impairment.
• We will ask you to complete a questionnaire before the examination and sign a consent form for the contrast injection if it is required.

Preparation:

• Spine, Extremities, and Joints: No preparation required.
  
• Head and Chest: Fast for 4 hours.
• Abdomen and Pelvis: Fast for 4 hours. One hour before your examination, drink 1 litre of water over 15 minutes.
• CT Angiography: Fast for 4 hours.

Complications: Allergic reactions to contrast material can occur, but significant reactions are rare and generally respond to adrenaline. Our staff members are equipped and trained 

to treat contrast reactions.

Your Images and Report: After your examination, you will be given a copy of the most pertinent images from your study. A report will be provided with the images or sent directly to your referring doctor by fax or email. We will store digital copies of all studies on our secure database for comparison with any future examinations. Please bring any previous X-rays with you for comparison. It is important that you return to your doctor with your examination results. Whether they are normal or abnormal, your doctor needs to know promptly so that a management plan can be formulated.

Special Instructions for Diabetics:

• If your examination requires fasting, book an early morning appointment and have your breakfast and diabetic medication after the examination.
• If your examination requires an intravenous injection of contrast medium, we need to know your renal function. Please bring along the results of your most recent blood test creatinine level.
• If you are taking metformin and receive an intravenous injection of contrast medium, you will be given special instructions to follow afterwards.
