CT (Computed Tomography) Scans

Molokai General Hospital provides CT (Computed Tomography) Scans, a diagnostic imaging procedure using a combination of x-rays and computer technology to produce cross-sectional images (often called slices) of organs and body parts such as the lungs, liver, kidneys, pancreas, pelvis, extremities, brain, spine and blood vessels. CT scans offer more detailed images of the human anatomy than traditional x-rays. Therefore, diseases and abnormalities may be caught at their beginning stages, allowing for earlier intervention and treatment.

Are there any patient restrictions for CT scanning?

Some conditions may limit the use of the CT scan. The CT technologist will need to know if you have any of the following conditions: allergies, kidney disease, congestive heart failure, diabetes, hypertension (high blood pressure), pregnancy, or weigh over 450 lbs.

What is contrast?

Depending on the type of procedure being done, a contrast agent, administered orally or through an IV injection, may be used to give a clearer image of the scan. The contrast may cause a temporary warm sensation or metallic taste in your mouth.

What should I do to prepare?

  • Your doctor will tell you if fasting prior to your exam is necessary. If so, you may be asked to abstain from food for 4 to 6 hours before your appointment.
  • You may have clear liquids (black coffee, tea, broth, clear soup or juice) in moderate amounts.
  • If you are not instructed to abstain from food, eat normally and take any prescribed medication.
  • Plan to arrive at the Radiology Department at least 30 minutes prior to your scheduled appointment.
  • When you check in to your appointment, you will be asked to complete a brief questionnaire about your medical history, medications, allergies and insurance. A CT technologist will explain the test and answer any questions.
  • Please bring any CAT Scans, MRI, Nuclear Medicine or x-rays that have been done at other facilities for comparison.
  • You may be asked to remove metal objects such as jewelry and change into a hospital gown.
  • Depending on the type of exam, the length of the actual procedure will typically be between 10 and 45 minutes.

What happens after the scan?

Once you are released, you may go about your normal activities without restriction. A formal written report of your scan will be sent to your requesting doctor, who will discuss the results with you and answer any questions.

When will I get the results of the scan?

Your films will be read by a radiologist and the report sent to your doctor. Your doctor will contact you with the results and answer any questions you may have.
