Myocardial Viability PET Scan
Your doctor has ordered a myocardial viability PET scan to measure myocardial glucose metabolism using FDG. Our team of subspecialty-trained doctors, nurses and technologists is led by Daniel S. Berman, MD, chief of Cardiac Imaging and Nuclear Cardiology.
Before Your Exam
Non-diabetics: Do not eat or drink for six hours before your appointment. Water is OK.
Non-insulin-dependent diabetics: If you are on oral diabetes medications, please do not eat or drink after midnight. Water is OK. Also, if applicable:
- You may take metformin (Glucophage®), pioglitazone (Actos®) and rosiglitazone (Avandia®) as scheduled.
- Reduce sulfonylureas (e.g., glimepiride, glipizide, glyburide) to a half dose on the morning of your study.
- Do not take sitagliptin (Januvia®) or saxagliptin (Onglyza®) on the morning of your appointment.
Insulin-dependent diabetics: Please follow your normal dietary schedule. Also, as applicable (consult with your doctor regarding adjusting the insulin use recommendations below):
- Reduce PM doses of insulin glargine (Lantus®) and Levemir® by half the evening before the study.
- Reduce AM dose of intermediate or long-acting insulin (i.e., NPH, Levemir®, insulin combos, such as 70/30, 75/25, etc.) or Lantus® by half the morning of the study.
- Take half basal dose of insulin pump on day of study.
- Note: You should not take the following medications until right before you eat a normal meal: nateglinide (Starlix®), repaglinide (Prandin®), pramlintide (Symlin®), exenatide (Byetta®) or liraglutide (Victoza®).
Please leave your jewelry and valuables at home.
During Your Exam
- Your approximate visit time will be three to four hours.
- Upon arrival, the technologist will explain your procedure and answer any questions you may have.
- In order to achieve optimal images:
- You will be given glutol to drink
- You will also be given insulin
- You will receive an intravenous injection (in your vein) of a tracer dose of radioactive material
- The level of radioactivity is extremely low and has no side effects.
- During your scan, you will be required to lie flat on your back without moving.
- Using a special nuclear medicine scanner, pictures of your body will be obtained. It simply detects and records the distribution of the radioactive material in your body.
