Preparing for Your Nuclear Medicine Exam


  • You will be asked to follow the Limited Carbohydrate diet for the previous 24 hours before the date of your appointment.
  • Do not eat or drink anything, except water, for 6 hours before the exam. You may drink water, as much water as you can would be helpful, until arrival.
  • Avoid strenuous exercise the day prior to your appointment.
  • Routine medications may be taken, unless you have been instructed otherwise. If you are diabetic, you may take your diabetes medication no less than 4 hours prior to the exam.
  • Arrive 15-30 minutes before your PET scan.
  • The technologist will verify your identification and exam requested.
  • You will be given a contrast screening form to complete.
  • In certain situations, the doctor may order lab tests prior to contrast being given.
  • Commonly, contrast is injected into a vein to better define the images throughout the body. If the radiologist believes this is helpful, a small intravenous (IV) line is placed in an arm vein. Through this line, the contrast and the isotope will be injected. The contrast will be excreted through your kidneys.
