PET Cardiac Viability Patient Instructions

Upon Arrival at Imaging Central

  • The patient’s medical history and any prior studies will be reviewed.
  • The patient’s blood sugar level will be checked.
  • An imaging tracer called Flurodeoxyglucose (FDG) is administered by way of injection.
  • A brief resting period is required before the scanning begins. (Typically 2 hours) This resting period is necessary for the FDG to be distributed to the heart.

At the Time of Pet Scanning

  • The patient is positioned on the table.
  • The table is moved into a large opening in the PET scanner.
  • The patient is asked to lie still as the PET scanner acquires the images.
  • The time of the scan varies, but will typically range from 5-10 minutes.
  • Please note that this takes approximately 3 hours in total duration.

Patient Preparation

  • Patient must fast 8 hours before exam.
  • Medications can be taken with water.


  • Patient must fast 8 hours before exam.
  • Medication can be taken with water.
  • A desired blood glucose level of <120 is optimal at time of procedure. Any oral medication should thus be taken no less than 6 hours prior to arrival for test.
  • Please request the technologist speak to the patient (or nurse) if the patient is on insulin. (This is so we can properly communicate the timing of their insulin injection prior to arriving at Imaging Central.)


  • The PET Viability scan will be compared with any prior cardiac perfusion studies, i.e. rest/stress tests, or other viability scans.
  • The exam is interpreted by a board certified, fellowship trained, Radiologist. The results are then faxed and mailed to your physician as soon as they are available.
