A computed tomography (CT) scan allows doctors to see inside your body. It uses a combination of X-rays and a computer to create pictures of your organs, bones, and other tissues. It shows more detail than a regular X-ray.
CT scan is a non invasive procedure. A narrow X-ray beam is used which circles around the body part to be examined and produces a series of pictures. A computer uses this information to create a cross-sectional picture. A two dimensional image is produced which is like a slice of your body.
This process is repeated to produce a number of slices. The computer stacks these scans one on top of the other to create a detailed image of your organs, bones, or blood vessels. For example, a surgeon may use this type of scan to look at all sides of a tumor to prepare for an operation.
Your doctor might tell you not to eat or drink for a few hours before the procedure. You may also need to wear a hospital gown and remove any metal objects, such as jewelry. We follow the ALARA (as low as reasonably achievable) principle while carrying out CT scan procedures to ensure minimum required exposure of patients to the radiations. Information about pregnancy or possible pregnancy should be informed to the radiologist before undergoing the CT scan.
A radiology technologist will perform the CT scan. During the test, you’ll lie on a table inside a CT machine. As the table slowly moves through the scanner, the X-rays rotate around your body. It’s normal to hear a whirring or buzzing noise. Movement can blur the image, so you’ll be asked to stay very still. You may need to hold your breath at times. How long the scan takes will depend on what parts of your body are being scanned. It can take anywhere from a few minutes to a half-hour. In most cases it is an outpatient procedure. The patient will be able to communicate with the technologist at all time during the procedure through audio communication system. It is also used by the technologist to talk with patient during the procedure to provide any instructions.
