CT Scan

Computerized Tomography

A CT scan is an x-ray procedure that is enhanced by a computer and gives out a three-dimensional view (referred to as a “slice”) of a particular part of the body.

Why is CT used?

While dense tissue can block some areas during standard x-ray image procedures, CT scans create a three-dimensional view by using a computer to combine different slices, showing all bone and tissue.

What Can I Expect?

Contrast media is given to highlight various body parts and passes through the body within a day or two. It is usually given by mouth or injection. It is normal to feel a warm sensation as the dye makes its way through your body. The exam can last anywhere from 30-60 minutes while the computer generates the image. Radiation exposure and procedure times can vary depending on the factors relating to your case.

  • 1) Bring all the previous medical records, scans & X-Rays at the time of Scan Procedure.

Q. What can you expect during a CT scan?

Expect the exam to last no more than an hour, depending on the preparation needed and whether it includes the use of contrast medium. The scan itself may take just a few minutes.

  • During the CT scan you lie on a narrow table that slides through the opening of a large device called the gantry. The table can be raised, lowered or tilted. Straps and pillows may help you stay in position. During a CT scan of the head, the table may be fitted with a special cradle that holds your head still.
  • As the X-ray tube rotates around your body, the table slowly moves through the gantry. While the table is moving you may need to hold your breath to avoid blurring the images. You may hear clicking and whirring noises. Each rotation yields several images of thin slices of your body
  • During this time, a technologist in a shielded room supervises the CT scan and monitors the images as they appear on the computer screen. The technologist can see and hear you, and you can communicate via intercom.
  • If an infant or small child is having the CT scan, you may be allowed to stay with your child during the test. If so, you may be asked to wear a lead apron to shield you from X-ray exposure.
  • CT scans are painless. If your exam involves use of an intravenous contrast medium, you may feel a brief sensation of heat or experience a metallic taste in your mouth. If you receive contrast medium through an enema - to help highlight your lower gastrointestinal region - you may feel a sense of fullness orcramping.
  • After the exam you can return to your normal routine. If you were given a contrast medium, your doctor or the radiography staff may give you special instructions. These likely include drinking lots of fluids to help remove the medium from your body.
