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.

2025年2月26日 · 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 …

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.

2015年12月26日 · Radionuclide myocardial perfusion imaging (MPI) is a well-established, highly accurate, and reproducible noninvasive method to diagnose and assess functionally significant coronary artery disease (CAD). Extensive development and validation have brought this modality to the forefront of quantitative, noninvasive assessment of CAD.

Myocardial perfusion imaging (MPI) to diagnose coronary artery disease (CAD) is best performed in patients with intermediate pretest likelihood of disease; unfortunately, pretest likelihood is often overestimated, resulting in the inappropriate use of perfusion imaging.

Myocardial perfusion imaging (MPI) by single photon emission computed tomography (SPECT) investigates the pathophysiological consequences of luminal obstructive CAD, while multislice computed tomography coronary angiography (CTA) indicates the presence, extent and location of coronary atherosclerosis.

2011年7月1日 · This review incorporates some of the more recent advances in CT coronary angiography and myocardial perfusion imaging (MPI), including PET MPI, into a discussion of anatomic versus physiologic imaging and provides our perspective on how an anatomy-based testing strategy centered in CT coronary angiography versus a physiology-based testing ...

Stress myocardial perfusion imaging (MPI) with SPECT is a well-established modality capable of quantifying relative stress and rest myo-cardial perfusion and left ventricular function with estab-lished diagnostic accuracies and prognostic performance characteristics.

Over the last several decades, radionuclide myocardial perfusion imaging (MPI) with single photon emission tomography and positron emission tomography has been a mainstay for the evaluation of patients with known or suspected coronary artery disease ...

2013年1月1日 · Myocardial perfusion imaging (MPI) refers to the utilization of radiotracers to image regional myocardial perfusion from coronary artery blood flow to the heart muscle.
