CAT SCAN
How does CT work?
Computed Tomography (CT) imaging, also known as “CAT scanning”, is the workhorse imaging system in most radiology departments and diagnostic centers today. CT Imaging is fast and patient friendly. CT is based on a the variable absorption of x-rays by different tissues. A CT imaging system produces cross-sectional images or ‘slices’ of the different organs and body parts such as the lungs, liver, kidneys, pelvis, brain, spine, and blood vessels.
What should you do to prepare for a CT scan? Patients should wear comfortable, loose fitting clothes for their CT exam. Patient preparation
for a CT examination involves removing any articles of clothing or jewelry that might degrade the CT images, such as belts, earrings, bras, glasses, dentures, hairpins, zippers and snaps. In some cases the patient may be asked to
wear a gown.
What should I expect from my CT exam? Many CT examinations require the oral or intravenous administration of a contrast agent, which is a liquid material that enhances the images of the organs and / or blood vessels. If a contrast agent is required the patient will be given instructions on eating and drinking prior to the exam.
