A CT (Computed Tomography) scan is a medical imaging scan that uses a thin set of rotating x-rays to produce a digital cross sectional image of the body.
To obtain these images an x-ray tube rotates around your body whilst you lie flat down on a moving x-ray table.
A CT scan can be performed on any part of the body that your doctor wishes to see, to help in diagnosis of a problem, to better define a known problem or to monitor for a change.
There are many different protocols we can perform with variations in the amount of the body covered and the timing of the scan after an injection of contrast if this is used. We need to have information about the question which is being asked by your doctor for our doctor (Radiologist) to work out which is the most appropriate protocol for you to have.
During the examination you may be asked to hold your breath for short periods. For certain examinations you may also be required to have an injection of x-ray contrast media to enhance your organs or blood vessels. This is a routine procedure and involves a small cannula to be inserted into a vein in your arm. Upon arriving, depending on your CT examination you may be required to fill in a short questionnaire regarding your medical history and your allergies.
