Myocardial Perfusion Imaging (MPI) Test American Heart ...

Jul 30, 2015  Myocardial perfusion imaging (MPI) is a non-invasive imaging test that shows how well blood flows through (perfuses) your heart muscle. It can show areas of the heart muscle that aren’t getting enough blood flow. This test is often called a nuclear stress test. It can also show how well the heart muscle is pumping.

Combined Long- and Short-Axis Myocardial Perfusion ...

Purpose: To date, myocardial perfusion cardiovascular magnetic resonance (CMR) has been reported in single and multiple short-axis slices. Three short-axis planes can assess 16 segments of the standard 17-segment myocardial model, but this approach fails to assess the ventricular apex that requires at least one long-axis plane.

We developed a completely automatic technique to reorient transaxial images into short-axis (oblique) myocardial perfusion SPECT images. Methods: The algorithm starts by isolating (segmenting) the left ventricle (LV) myocardium using a combination of iterative clusterification and rule-based location/size/shape criteria. The three-dimensional, mid-myocardial LV surface is initially estimated ...
