2. How should I prepare for CT scan?

A CT scan is a computerized x-ray where a number of x-ray pictures are taken of the pelvic and abdominal area and fed into a computer to give a detailed picture of the inside of the body.

In some cases contrast may need to be given to obtain a clearer picture. This is usually injected into a vein in the arm. It may give a feeling of warmth and cause mild flushing of the skin. Once you are lying comfortably on the couch, the scan can be taken. The scan itself is painless, but it will mean you have to lie still for up to 10–15 minutes. Most people are able to go home as soon as their scan is over.

1. No fasting is required. However, no food 4 hours before the procedure may be useful.
2. If you are DM, keeping yourself hydrated is useful.

1. As the strong magnetic field used for MRI will pull on any ferromagnetic metal object implanted in the body, it is important that all metallic items including magnetic strips (e.g., in bank or credit cards) be removed before entering the scanning room.  The presence of metal will also degrade the MRI image and therefore has to be removed in order to optimize your examination.
2. In most cases surgical staples, plates, pins and screws pose no risk during MRI if they have been in place for more than four to six weeks.
3. If there is a doubt, a x-ray may be required to verify the presence of any metal in your body or head.
4. You are discouraged to apply make-up or sprays on your body or hair as these may contain metallic dust and affect the images.
5. You will be asked to fill in a pre-examination questionnaire to ensure that no significant medical history is forgotten and the staff is fully aware of any metal that may be in your body.
6. There is no need to fast unless a contrast injection is required. Please consult your doctor.
7. Do continue to take your regular medication unless otherwise directed.

4. How should I prepare for IVU (Intravenous Urogram)?

This test shows up abnormalities in the urinary system. It is done in the hospital x-ray department and takes about an hour. A dye is injected into a vein, usually in the arm, that travels through the bloodstream to the kidneys. The doctor can watch the passage of dye on an x-ray screen and pick up any abnormalities.

The dye may make you feel hot and flushed for a few minutes, but this feeling gradually disappears. You may feel some discomfort in your abdomen, but this will only be temporary. You should be able to go home as soon as the test is over.
