Myocardial Perfusion Imaging (MPI)
What is Myocardial Perfusion Imaging (MPI)? Myocardial perfusion imaging (MPI) is a non-invasive nuclear imaging technique that allows for the assessment of blood flow to the heart muscle. MPI uses a small amount of radioactive tracer, which is taken up by the myocardium. This process can be visualized using SPECT or PET.
MPI is often used in stress tests to visualize the extent of coronary artery disease by showing regions of decreased uptake. It can also be used to detect areas of previous myocardial damage in areas where no perfusion can be seen.
Advantages of Myocardial Perfusion Imaging (MPI)
- Non-invasive test that does not require catheterization or surgery.
- Early detection of coronary artery disease
- May be used to assess the effectiveness of treatment for heart disease.
