We offer the most advanced heart positron emission tomography (PET) myocardial perfusion imaging (MPI) scan techniques available. This test measures the blood flow that your heart receives. Your doctor uses a PET MPI exam if you’re having symptoms or are at risk for heart disease. The results of this exam will help your doctor decide if you need follow-up treatment. If you are already being treated for a heart-related condition, your doctor can use the results of this exam to help manage your treatment.
Cardiac PET images are the most accurate stress tests. There are many advantages to a PET MPI exam:
If your provider has requested a PET MPI test for you, it’s natural to have questions and concerns. Below, we’ve provided answers to the most frequently asked questions about this exam and provide you with the information you need to feel informed and prepared.
During your exam, you’ll receive a small amount of radiation exposure, which is considered safe by the National Council on Radiation Protection and Measurements.
Our scanner uses the lowest-possible radiation dose and is low in comparison to other radiation-based tests. This is especially important if you need regular tests that involve radiation.
Do not eat or drink anything six hours before your scan. You may drink water only before your exam. Please refrain from nicotine and caffeine 12 hours prior to your scan.
Your doctor may tell you to stop using certain medications, such as nitrates and beta blockers.
If you have diabetes, talk to your doctor before the exam. They may give you special instructions to prepare for your scan.
Please allow at least an hour for the exam. You should arrive 30 minutes prior to your exam to register and review your medical information with your care team. The actual test usually takes about 30 minutes. It’s important to arrive on time.
Please let your care team know if you’re nervous or if you’re claustrophobic. We can help you feel more comfortable during your exam. Your care team can guide you through relaxation techniques. You may also bring relaxing music to listen to during your exam, or we can play music for you.
If possible, please bring all your previous MPI films/studies with you if they weren’t performed at St. Luke’s.
Please wear comfortable, nonmetallic clothing.
Please let your doctor know if you might be pregnant or are currently breastfeeding prior to the exam.
