A CT scan, also known as computed tomography scan, makes use of computer-processed combinations of many X-Ray measurements taken from different angles to produce cross-sectional images (virtual “slices”) of specific areas of a scanned object, allowing the user to see inside the object without cutting.
It is a diagnostic imaging procedure that combines the use of x-rays with computer technology to produce cross-sectional images (“slices”) of the body.
The images produced are more detailed than those of an ordinary x-ray.
THE CT SCAN:
- You will be lying flat on a table usually on your back, stomach or side.
- Depending on the study scheduled, you may be given an injection of intravenous contrast during the CT examination.
- The table will move slowly through the machine as the actual CT scanning is performed. You may be asked to hold your breath at different times during the exam.
- The actual examination time can vary from a few minutes to about an hour, depending on the procedure. However, the actual x-ray exposure time is minimal.
