How does a myocardial perfusion scan work? A myocardial perfusion scan uses a special chemical called a radionuclide. A radionuclide (sometimes called a radioisotope or isotope) is a chemical which sends out (emits) a type of radioactivity called gamma rays. In a myocardial perfusion scan a tiny amount of radionuclide is put into the body ...
In the 1990s, positron emission tomography (PET) MPI emerged as an alternative to SPECT MPI for assessing regional myocardial perfusion using vasodilator stress and relatively short-lived positron-emitting …
The value of radionuclide myocardial perfusion imaging (rMPI) with single-photon emission computed tomography (SPECT) for the diagnosis and risk stratification of coronary artery disease (CAD) is well-established. However, the full clinical potential of rMPI has not been realized due to numerous factors that result in image artifacts.
Myocardial perfusion imaging by nuclear cardiology is widely validated for the diagnosis, risk stratification, and management of patients with suspected or known coronary artery disease. Numerous radiopharmaceuticals are available for single-photon emission computed tomography and PET modalities. Each tracer shows advantages and limitations that should be …
Since the publication of the European Association of Nuclear Medicine (EANM) procedural guidelines for radionuclide myocardial perfusion imaging (MPI) in 2005, many small and some larger steps of progress have been made, improving MPI procedures. In this paper, the major changes from the updated 2015 procedural guidelines are highlighted, focusing on the …
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.
Radionuclide myocardial perfusion imaging (rMPI) enables evaluation of cardiac perfusion and function at rest and during dynamic exercise or pharmacologic stress for the diagnosis and management of patients with known or suspected coronary heart disease. Radionuclide MPI requires the administration of a radioactive perfusion tracer (also called ...

(Myocardial Perfusion Scan)? A nuclear stress test, also called a myocardial perfusion scan, is a type of nuclear medicine procedure. This means that a tiny amount of a radioactive substance, called a radionuclide, is used to evaluate the heart's function and blood flow.
A prospective comparison of rubidium-82 PET and thallium-201 SPECT myocardial perfusion imaging utilizing a single dipyridamole stress in the diagnosis of coronary artery disease. ...

Unless otherwise noted, all indications referred to SPECT MPI and positron emission tomography myocardial perfusion imaging. All radionuclide perfusion imaging indications also assume the use of ECG gating, whenever possible, with determination of global ventricular function (i.e., left ventricular ejection fraction) and regional wall motion as ...
Abstract Background. We hypothesized that among patients presenting with dyspnea on exertion (DOE), those who were found to have hyperdynamic left ventricle (i.e. LVEF ≥ 70%) on stress radionuclide myocardial perfusion imaging (RNMPI), are more likely to have features of diastolic dysfunction on transthoracic echocardiography.
Radionuclide myocardial perfusion imaging (RMPI) has served as a clinical mainstay in the management of patients with known or suspected coronary artery disease (CAD) for more …
Simultaneous dual-radionuclide myocardial perfusion/innervation SPECT imaging can provide important information about mismatch between scar tissue and denervated regions. The Siemens IQ-SPECT system developed for cardiac imaging uses a multifocal SMARTZOOM collimator to achieve a four-fold sensitivity for the cardiac region compared to a ...
The 2 types of radionuclide studies commonly used for cardiac evaluation are myocardial perfusion imaging (MPI) and cardiac blood pool imaging (multiple gated acquisition scanning (MUGA), ventriculography). MPI is used primarily for the evaluation of …

Photon attenuation due to absorption by soft tissue is one of the major factors that adversely affect the diagnostic accuracy of radionuclide-based myocardial perfusion imaging (MPI). Its primary effect is to reduce diagnostic specificity of perfusion defects. 1 The probability that a photon will be transmitted through tissue is a function of ...
Myocardial perfusion imaging (MPI) is a non-invasive imaging test that shows how well blood flows through your heart muscle. It can show areas of the heart muscle that aren't getting enough blood flow. It can also show how well the heart muscle is pumping. This test is often called a nuclear …
