What to Expect
Most CT exams involve changing into a procedure gown and lying on a table that moves through the gantry, the device that holds the x-ray tube. Our technical staff will explain everything before starting, including any contrast material that may be injected through a vein in your arm. During the exam, you’ll hear the table move and the tube rotate and staff will guide you through a microphone from the control room — including instructions like holding your breath when asked. Most procedures last only a few minutes with very little, if any, discomfort.
Preparing for Your Visit
Many CT exams require no specific preparation. Some do involve dietary restrictions or drinking oral contrast material beforehand — you’ll be given exact instructions when your exam is scheduled. Side effects, when they occur, are generally mild and related to contrast material (a warm sensation, urge to urinate, or metallic taste that passes quickly). Please tell your provider about any allergies, diabetes or kidney conditions before your scan.
