Myocardial perfusion imaging or scanning (also referred to as MPI or MPS) is a nuclear medicine procedure that illustrates the function of the heart muscle (myocardium). [1] It evaluates many heart conditions, such as coronary artery disease (CAD), [2] hypertrophic cardiomyopathy and heart wall motion abnormalities.

Feb 26, 2025 · Myocardial perfusion imaging (MPI) is a test that shows how well blood flows through the heart muscle. There are two kinds of MPI: PET scan and SPECT scan. Both PET and SPECT are nuclear medicine procedures. The scans can help diagnose or detect many heart conditions. What is a myocardial perfusion imaging test?

What is a stress myocardial perfusion scan? Myocardial perfusion is an imaging test. It's also called a nuclear stress test. It is done to show how well blood flows through the heart muscle. It also shows how well the heart muscle is pumping. For example, after a heart attack, it may be done to find areas of damaged heart muscle.

Interpreting myocardial perfusion SPECT images involves a systematic comparison of rest and stress images to assess myocardial ischemia and infarction. The key steps in this process are outlined below.

Myocardial perfusion single photon emission-computed tomography (MPS) has been one of the most important and common non-invasive diagnostic cardiac test. Gated MPS provides simultaneous assessment of myocardial perfusion and function with only one study.

Nov 18, 2024 · Myocardial perfusion scanning is crucial for diagnostic and therapeutic decision-making in cardiac diseases, especially coronary artery disease (CAD). The term "myocardial perfusion scanning" refers to a group of noninvasive imaging tests that help clinicians assess blood flow to the myocardium.

Myocardial perfusion is an imaging test. It's also called a nuclear stress test. It is done to show how well blood flows through the heart muscle. It also shows how well the heart muscle is pumping. For example, after a heart attack, your doctor may order this test to find areas of damaged heart muscle.

Nuclear medicine has long played an important role in the noninvasive evaluation of known or suspected coronary artery disease. The devel-opment of single photon emission computed tomography (SPECT) led to improved assessments of myocardial perfusion, and the use of …

MPSImage objects are at their core MTLTexture objects; however, whereas MTLTexture objects commonly represent image or texel data, an MPSImage object is a more abstract representation of image features.

Although myocardial perfusion SPECT (MPS) imaging is widely used in current clinical practice, it suffers from some fundamental limitations including long image acquisition, low image resolution, and patient radiation dose.
