SPECT stands for “Single Photon Emission Computed Tomography.” It is similar to X-ray technology, but instead of providing a two-dimensional image, it provides a clear 3D view. Tomography refers to a process of displaying a cross-section of the heart or another body area.
What is Myocardial Perfusion Imaging?
Myocardial perfusion imaging, or MPI, is another name for a SPECT test. It is also commonly referred to as a “nuclear stress test.” Another type of myocardial perfusion imaging test is a PET scan, or “positron emission tomography.” The SPECT test can be useful in determining the source of chest pain and whether it is the result of a lack of sufficient blood flow to the heart as the result of blocked arteries. If you have experienced chest pain, this test could be just one of the diagnostic tests you need if your SPECT scan reveals abnormalities in blood flow to the heart.
