What is CT scanning of the body?
CT scanning – also called CAT scanning – is a non-invasive, painless medical test that helps physicians diagnose and treat medical conditions.
CT scans of internal organs, bone, soft tissue and blood vessels provide greater clarity than conventional x-ray exams.
Using specialized equipment and expertise to create and interpret CT scans of the body, radiologists can more easily diagnose problems such as cancers, cardiovascular disease, infectious disease, trauma and musculoskeletal disorders.
CT imaging uses special x-ray equipment and a computer to produce multiple images or pictures of the inside of the body and join them together in cross-sectional views of the area being studied. The images can then be examined on a computer monitor or printed. The data can also be transformed into three-dimensional and four-dimensional volume- rendered images.

How is the CT scan performed?
The radiologic technologist begins by positioning you on the CT examination table, usually lying flat on your back or possibly on your side or on your stomach. Straps and pillows may be used to help maintain the correct position and to help you hold still during the exam.
If a contrast material is used, it will be swallowed and/or injected through an intravenous line (IV) depending on the type of examination.
Next, the table will move quickly through the scanner to determine the correct starting position for the scans. Then, the table will move slowly through the machine as the actual
CT scanning is performed. You may be asked to hold your breath during the scanning.
How should I prepare for the CT scan?
You should wear comfortable, loose-fitting clothing to your exam. You may be given a gown to wear during the procedure. Metal objects including jewelry, eyeglasses, and hairpins may affect the CT images and should be removed prior to your exam. You may also be asked to remove hearing aids and removable dental work.
If IV contrast material is to be administered for your CT examination you will be asked questions in regard to the contrast and also asked to sign a contrast consent form.
You should inform your physician if you take any of the following medications: Glucophage, Avandamet, Metaglip, Riomet and Glucovance. These medications should be held for 48 hours after the exam and not resumed until checking with your referring physician if you receive IV contrast material for your CT scan.
Your physician also needs to know if you take medications containing Amiodarone such as Cardarone or Pacerone, as IV contrast material cannot be administered if these drugs are being taken.
Report to your physician any allergies your may have, especially to iodine-containing contrast materials.
Also inform your doctor of any recent illnesses or other medical conditions, and if you have a history of heart disease, asthma, diabetes, or kidney disease. Any of these conditions may increase the risk of an unusual adverse effect. A simple blood test may be necessary prior to your study, if you have a history of kidney disease.
Women should always inform their physician or technologist if there is any possibility that they are pregnant.
Who interprets the results and how do I get them?
A radiologist, a physician specifically trained to supervise and interpret radiology examinations, will analyze the images and send the results to your referring physician, who will share the results with you.
