What is an IV Contrast CT Scan?
IV (Intravenous) contrast scan is a type of scan in which contrast material is used to obtain sharper and better images of the area being scanned. Contrast materials such as iodine-based and barium sulfate are used frequently in X-ray, CT imaging scans. Contrast scans are the newer forms of the standard CT scan, which require more care and vigilance while taking the test.
Purpose of IV Contrast CT Scan?
IV contrast is the advanced form of CT scan in which the physician suggests taking contrast to get a clear and precise picture of the scanning area. In CT scan contrast patients will be advised not to eat anything before 4 hours of the test and also avoid any kind of drinking before 2 hours of the test. The patient will be administered iodine-based or barium sulphate-based contrast intravenously (IV).
Also, a patient has to provide the following information:
- Blood test: A blood test will confirm that the contrast will be safe to ingest.
- Diet: You will be required to eat only a particular type of foods and liquids prior to the scan and what not to do.
- Medication: Inform the doctor about the medications the patient is taking, since some of these medications have allergic reactions with the contrast. Eg. Diabetic medication metformin (Glucophage) needs to be stopped for a period of time prior to the scan.
