CT Scan Brain/Head

C.T. Scan - Computerized Tomography Scan

A C.T. (Computerized Tomography) Scan is a test that uses a computer to make an x-ray image or picture of a very thin section of the body.

CT Scan Procedure

You will lie on a table that can be moved into the doughnut-like scanner opening. Your head may be held by a strap to keep you from moving during the scan. After your head is positioned, the camera inside the scanner will move around the part being tested. An x-ray picture will be taken, and the information processed by a computer so that your head can be viewed in thin cross-sectional slices. It is very important that you do not move during the scan as this may blur the picture. During the scan, you will hear clicking noises; these are normal scanner sounds. A contrast (dye) may be given at some time during the test.

Procedure time: 30 minutes

Patient Preparation Instructions:

  1. Do not eat or drink anything for two (2) hours before the test.
  2. Any woman who is pregnant, or thinks she might be, should let her doctor know before having the scan.
  3. Please inform the technologist of any known allergies.
  4. Do not bring jewelry or large amounts of money with you.
  5. You may be asked to sign a consent form for the scan.
  6. Relax and follow the directions given to you by the Medical Imaging staff. Please remember to lie still during the test to get a clear picture.
  7. An iodine-containing dye may be injected. If you develop hives, itching, or any other unusual symptoms within 24 hours, please get in touch with either your family doctor, the Radiology Department, or be seen in the Emergency Department. This may be an allergic reaction.
  8. You will be able to leave the x-ray department when the test is finished. Discharge instructions will be given to outpatients.
  9. The Radiologist (x-ray doctor) will “read” the scan and give the results to your doctor. Your doctor will share the results of this test with you in 2-3 days; feel free to ask the doctor if you have any questions.
  10. If you have any questions about getting ready for your test, please call 419-394-3335, ext. 3550 for assistance.
