What is CT Scanning of the Body?
Computed tomography (CT) is a medical imaging method employing tomography. Digital geometry processing is used to generate a three-dimensional image of the inside of an object from a large series of two-dimensional X-ray images taken around a single axis of rotation.
What are some common uses of the procedure?
A CT scan is one of the best and fastest tools for studying the chest, head and sinus, abdomen, and pelvis because it provides detailed, cross-sectional views of all types of tissue.
How should I prepare?
If instructed you may be asked to have no food or drink 4 hours prior to the test. You should inform your physician of any medications you are taking and if you have any allergies. If you have a known allergy to contrast material, or “dye,” your doctor may prescribe medications to reduce the risk of an allergic reaction.You should wear comfortable, loose-fitting clothing to your exam.
You may be given a gown to wear during the procedure. Metal objects including jewelry, eyeglasses, dentures and hairpins may affect the CT images and should be left at home or removed prior to your exam. You may also be asked to remove hearing aids and removable dental work.
Patients on Glucophage, Metformin, Avandamet, Glucovance, and Metaglip:
You have received intravenous contrast and have been instructed to discontinue your Glucophage (including Metformin, Avandamet, Glucovance, and Metaglip) for 48 hours. Please contact your physician’s office to inform them of this injection and to have a serum creatine blood test drawn.
Current recommendations are that Glucophage (including Metformin, Avandamet, Glucovance, and Metaglip) should not be re-started until after kidney function has been re-evaluated and found to be normal. If you have any questions, please call: 407-841-1100 and ask to speak with a technologist.
