PET Myocardial Perfusion Imaging
What is PET Myocardial Perfusion Imaging
PET Myocardial Perfusion Imaging is a diagnostic test that uses Positron Emission Tomography (PET) to visualize blood flow to the heart muscle. It helps detect coronary artery disease (CAD) by providing detailed images of the heart’s blood supply. The test uses a radioactive isotope, Rubidium-82, which is injected into the bloodstream. The PET scanner captures the isotope to create high-resolution images of the heart, allowing cardiologists to assess blood flow, detect blockages, and evaluate the heart’s overall health.
How the test Works
Benefits
- Faster and More Efficient: PET typically takes 30 minutes, while SPECT can take several hours.
- Higher Accuracy and Sensitivity: PET provides superior imaging resolution and is less affected by soft tissue artifacts, making it ideal for individuals with large body sizes.
- Minimal Radiation Exposure: The short half-life of Rubidium-82 means there is no residual radiation left in the body, making it safer for patients.
- Precise Blood Flow Mapping: PET offers highly detailed images of heart blood flow, allowing cardiologists to detect even subtle signs of CAD.
What to Expect During the test
During the procedure, you will lie still on a bed. The technician will administer regadenoson and the radioactive isotope. The test is completed in one session with no long waiting periods. The images obtained provide detailed information on the heart’s perfusion and blood supply, especially for patients at risk of CAD.
