Registration Process and Forms
Click here to download pertinent forms that are required for your registration and various exams. On the day of your exam, please arrive 15 minutes before your appointment, in order to allow for registration and processing of paperwork. You must check in, and register with the clerical staff. Your insurance card is required for registration, and depending on your insurance carrier, you may have a
co-pay. If you have had X-rays or scans (or any exams on compact discs) to diagnose this same or similar problem at another facility, please make sure you bring them with you. These films or scans will be kept for reporting and then mailed back to the facility of origin.

Patient Preparation
After registration, when it is time for your examination, a technologist will escort you to the dressing room if you need to change into a hospital gown for your examination. If you have a condition that requires you to take medication on a regular basis, you should keep to your regular medication schedule. The only exception is Metformin or Glucophage, they must be held for 48 hours following the CT examination if you receive an IV contrast injection. Some examinations require that you drink barium sulfate, you will need to follow the directions on how and when to drink your barium. A dressing room is provided for secure lock up of your clothing and valuables.

Exam Procedure
The technologist will go over the CT screening form with you, explain the procedure and answer any questions that you might have. You will then be escorted into the scan room. You will hear humming noises which are produced during the scanner’s operation. The scan room has a large donut-shaped gantry with a padded table that moves you into the center of the machine once you are positioned. Whether or not you go into the machine head first or feet first, as well as, how far in you go, is determined by the type of exam being performed. The scanner is equipped with a two-way intercom for communication with the technologist. It is very important that you remain relaxed and try not to move during the scan. Even very slight movement of the part being scanned can cause very distorted images that will have to be repeated. For some exams, you may be asked to hold your breath for 10-30 seconds as the pictures are taken.

Length of Scan
The exam consists of several different scans that vary in length and type of sound they produce. Most exams take 5 to 15 minutes, but there are a few exams that take 20 to 30 minutes. Some exams may also require the injection of a contrast agent called Isovue. This contrast agent is a colorless fluid, which is injected into a vein in your arm. The contrast agent is very safe; its purpose is to make the details in the CT images clearer and is standard for some types of examinations. If you require a contrast injection, the technologist will take you out of the scanner and inject it into a vein in your arm. The technologist will then return you to your original position in the scanner. Since we need the images before and after the injection to match, it is important that you do not move while the contrast medium is being administered. Please note, each CT scan is individualized and tailored to each patient’s needs. If you have had a CT scan before do not be concerned if this one is longer or shorter.

After the Exam
After the exam, the radiologist and technologist will review the images to ensure diagnostic quality. If the quality is acceptable, you can go home. If more images are needed, they will usually be taken right away.

If you have had an IV injection during your exam it will be eliminated by your kidneys within the next few hours. Increasing your intake of water during this time would be beneficial. There are no lasting effects from the contrast injection, however, if you feel that you are having an adverse reaction, please call you physician.

The barium or oral contrast that you may have had to drink for your study can sometimes be constipating. Increasing your fluids will help prevent this. If the oral contrast you drank is white, your stools may be chalky white and light-colored for the next few days.

Your CT Report
Your scan will be reviewed by a radiologist. The CT report will be sent to your physician, and your physician will be the one to discuss the results with you.
