DIAGNOSTIC IMAGING - COMPUTED TOMOGRAPHY (CT) SCAN

What is a CT Scan?
Computed Tomography (CT) is an x-ray technique that uses a special scanner and computer to create cross-sectional images of parts of your body.

How Do I Prepare for My CT Scan?
Preparation varies depending on the CT exam you are having. You may be given either an oral or intravenous contrast media (dye) that highlights the area being scanned.

What Can I Expect During The Exam?
When you enter the exam room, you will be asked to lie on the scanner table. A radiologic technologist, who is trained in the use of this specialized equipment, will assist you. The table will then be moved into the scanner's opening to perfectly align the portion of your head or body to be studied. After each image is taken, the table will advance slightly to scan the next portion.

As you are moved through the scanner, relax and remain as still as possible. If a scan of your chest or abdomen is being done, breathing instructions will be given to you - this is to avoid any blurring of the image created by your breathing movements. The technologist will tell you when to hold your breath, and when you may breathe normally.

How Long Will My CT Scan Take?
The length of your CT exam depends on your needs. An exam of the head or spine averages 15 minutes. An exam of the abdomen/pelvis averages 30 minutes.

What Will Happen Following My CT Exam?
You may resume regular diet and medication schedules immediately after the exam, unless your physician has advised you otherwise. If you received intravenous contrast media you need to increase your intake of fluids the rest of the day.

How Do I Find Out The Results of My CT Scan?
A radiologist will review your CT scan. The radiologist will then report the results to your physician, who will discuss the findings with you.

For CT Scans of the Abdomen/Pelvis, Oral Contrast is Required:

• Please take one bottle of Redi Cat after your evening meal the night before the CT Scan is scheduled.
• Also take one bottle of Redi Cat the morning of your exam, one half-hour prior to your appointment time.

It is important that the entire amount of Redi Cat be taken, to insure your test is complete. Medications may be taken with a clear liquid diet until the time of your appointment.

For CT Scans Requiring Intravenous (IV) Contrast:

• It is important to notify the technologist or physician if you have any allergies to iodine, shellfish, or previous IV injection.
• Intravenous dye may cause warm sensations throughout your body, as well as a dry, bitter taste. These sensations last between 5 and 10 seconds, and disappear quickly.

Important Considerations:
If you have an allergy to iodine, or have had an allergic reaction to a previous contrast (dye) exam, please tell your physician before you have this exam.

Any woman who is pregnant, or suspects she may be pregnant, should let her physician know before scheduling this exam.
