Many tests, such as those involving the spine, bones, joints, sinuses, or kidney stones, require no preparation. Some CT tests include the use of a dye or “contrast” to help body parts show up more clearly on the image. If so, you will be asked to swallow the dye in a drink, or it will be injected into your vein. If the contrast is injected, you may feel a warm sensation throughout your body.
If your test needs contrast, please do not eat or drink for 4 hours before the exam. Drink plenty of fluids after the test to help your body get rid of the dye. We will provide detailed instructions when you are scheduled for your exam.
