A Computed Tomography (CT) scan is a procedure that results in a cross-sectional picture of a specific body part or organ. A thin x-ray beam moves rapidly around the designated area, generating multiple images from different angles.
An electronic detector relays these images to a computer, which then constructs an image on a computer screen. CT scans are completely painless. When contrast media is injected, you may feel slight discomfort from the needle.
What is Contrast Media?
Contrast Media is an iodine solution that is injected into your vein to allow better imaging of blood vessels and organs.
What about my medical history?
Be sure to tell us if you’re pregnant, diabetic, allergic to any foods, drugs or are being treated for any type of infection, cancer or have a history of cancer.
We’ll also need to know if you’ve had any contrast media in the past and if you had any side effects at that time.
How do I prepare for a CT scan?
If contrast media will be used during your scan, you may be asked to fast 3-4 hours beforehand. You may also be asked not to drink anything for 4 hours before the exam.
For a body scan, you’ll be asked to wear a gown and to remove all jewelry. For a head scan wear loose, comfortable clothing and remove dentures, glasses, hearing aids, earrings, hairpins and any other items that may be detected by the x-ray beam.
If you are a diabetic and currently take medication for your diabetes (with the exception of insulin), you will need to discontinue your medication the day of your test and for 48 hours after the exam.
Please do not take any NSAIDs (such as Advil, Motrin, Alleve, Ibuprofen) for 48 hours before or after your exam. Use of these medications can resume only after renal (kidney) function has been re-evaluated and found to be normal (patients will need to see their referring physician to establish this).
Contact your referring physician with any questions regarding these guidelines.
If you meet any of the following criteria, we MUST have a copy of your recent bloodwork (within 30 days of your scheduled exam) to include BUN, Creatinine & GFR:
- DIABETIC AND ON MEDICATION FOR DIABETES
- 65 YEARS OF AGE OR OLDER
- KIDNEY DISEASE
- CONGESTIVE HEART FAILURE
- MULTIPLE MYELOMA
Please contact your referring physician to obtain a prescription for lab work. Lab work must be completed at a local laboratory no more than 14 days prior to your scheduled exam.
