Prep is required for MRCP (magnetic resonance cholangio-pancreatography) - patient must not eat or drink anything for 4 hours prior to the exam and the patient will be asked to drink oral contrast just prior to the exam. All other exams: Preparation is not required. Important Notes: Some MRI exams require an injection of I.V. contrast gadolinium. Scans will be performed without the contrast and then the contrast will be injected into a small vein in your arm. Scans will be performed again after the injection of contrast for comparison. At the time of the exam the technologist will explain the contrast procedure in greater detail and will also ask you about your allergies and prior sensitivity to contrast agents. |
