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.
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.
