Radionuclide ventriculography (RVG, RNV) or radionuclide angiography (RNA) is often referred to as a MUGA (multiple-gated acquisition) scan. It is a type of nuclear imaging test. This scan shows how well your heart is pumping. Quick facts
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.
12/27/2018 · Radionuclide stress test: A procedure that involves injecting a radioactive isotope, typically thallium or cardiolyte, into the patient's vein after which an image of the patient's heart becomes visible with a special camera. The radioactive isotopes are absorbed by the normal heart muscle. Nuclear images are obtained in the resting condition, and again immediately following exercise.
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 . It evaluates many heart conditions, such as coronary artery disease (CAD), hypertrophic cardiomyopathy and heart wall motion abnormalities.
QRS pattern and improvement in right and left ventricular function after cardiac resynchronization therapy: a radionuclide study. ... Cardiac resynchronization therapy (CRT) reduces morbidity and mortality in patients ... Radionuclide angiography with phase analysis was used to evaluate mechanical dyssynchrony and to measure LVEF and RVEF.

1/28/2009 · This review summarizes the value of cardiac radionuclide imaging in stable coronary artery disease (CAD) and acute coronary syndromes (ACSs) with a particular emphasis on the role of MPS, the most commonly used technique of nuclear cardiology. Principles of MPS
Cardiac Nuclear Medicine. Cardiac nuclear medicine imaging evaluates the heart for coronary artery disease and cardiomyopathy (diseases of the heart muscle). It also may be used to help determine whether the heart has been damaged by chemotherapy or radiotherapy.

A nuclear heart scan is an imaging test that uses special cameras and a radioactive substance called a tracer to create pictures of your heart. The test can detect problems with blood flow in the heart tissue and can diagnose ischemic heart disease. It can also assess how well your heart pumps blood to your body.

4/11/2012 · Predicting response to cardiac resynchronization therapy (CRT) remains a challenge. We evaluated the role of baseline QRS pattern to predict response in terms of improvement in biventricular ejection fraction (EF). Consecutive patients (pts) undergoing CRT implantation underwent radionuclide angiography at baseline and at mid-term follow-up.
CARDIAC RADIONUCLIDE IMAGING–ANEW TECHNOLOGY IN NEED OF SCRUTINY Cardiac radionuclide imaging encompasses a variety of techniques designed to provide infor-mation of value in detecting the presence and ex-tent of cardiac disease. All of these techniques are noninvasive and relatively risk free. All en-tail the injection of a ...
Cardiac performance was studied by radionuclide angiography at rest and during exercise in 22 adolescents with sickle cell (SC) anemia and the results were compared with those in 12 control subjects. At rest, cardiac contractility was normal; cardiac output and end-diastolic volume were increased.
