Computed Tomography (CT Scan)

Computed Tomography - CT ScanComputed Tomography (CT) is performed by specially trained CT technologists. With CT imaging, multiple images (slices) of the body are taken. The simplest explaination of this technology is to imagine that your body is like a loaf of bread. This loaf has many slices to it and a CT scan allows us to look at each individual slice in great detail.

Images are taken at specific intervals and are used to create two-dimensional images of soft tissues and other structures not captured in conventional X-rays. 3-D images can be produced in some cases depending on the type of equipment and computer software available. CT scans may be taken of any area of the body including the head, neck, chest, abdomen, pelvis, legs and arms. CT scans are particularly useful in diagnostic analysis of organs, bones, musculoskeletal disorders, cardiovascular disease, infectious diseases, and cancer.
 
The CT machine is a large piece of equipment with a hole in the centre for the body to pass through. When you enter the scanning room, the technologist will ask you questions about possible allergies and any medications you may be taking. The procedure will also be explained to you. The CT technologist will position you on the table. The table will slide in and out of the centre hole of the CT machine. The machine rotates around your body to take images and makes clicking and whirring noises as it moves.

During the procedure, it is important that you remain still while imaging takes place to avoid blurred pictures. You may be asked to hold your breath during the procedure. This will be explained to you by the technologist. Special precautions are taken for patients with allergies, diabetics, children, and patients taking certain medications. On occasion, children may require a mild sedation or even general anesthesia and must be accompanied by a parent or guardian.
