CT (Computed Tomography) Scan

Computed tomography (CT) combines the use of X-rays with the latest computer technology to take detailed images of any body part. Using a series of X-ray beams, the CT scanner creates cross-sectional images. A computer then reconstructs the "slices" to produce the actual pictures. Considering that some slices are as thin as half a centimeter, a CT scan offers much more image detail than a traditional X-ray, which means your doctor obtains detailed images to help make the most accurate diagnosis.

What Should You Expect During a CT Scan?

During the scan, the patient will be asked to rest motionless on a padded table for 5 to 15 minutes depending on the area of the body to be scanned. The table moves every few seconds as the images are obtained. The patient will hear faint humming and clicking sounds. Once the images are taken, a radiologist will review the images to ensure all of the area has been covered. Sometimes because of breathing or motion inside the body additional images are needed. Additional images do not mean there is a problem.

Preparations & Considerations

For the intravenous contrast studies, do not eat 4 hours prior to the exam. You should wear loose, comfortable clothing, avoiding garments that have zippers, belts, or buttons made of metal. You may be asked to wear a gown during the procedure. You will be asked to remove keys and jewelry from the area being scanned. 

If you have a history of claustrophobia, an allergy to iodinated contrast, asthma, or a strong allergic history, please notify our office when scheduling the examination. Premedication may be necessary depending on the clinical history. If premedication is indicated, the radiologist or referring physician can call your pharmacy. Upon arrival at the office, please notify the front desk staff and the technologist that you have an allergic history, or have been premedicated. 

Women should always inform their physicians and the technologist if there is any possibility of pregnancy.
