Nuclear ventriculography - Results

Alternative Names

Cardiac blood pooling imaging; Heart scan - nuclear; Radionuclide ventriculography (RNV); Multiple gate acquisition scan (MUGA); Nuclear cardiology

Normal Values:

Normal results indicate that the heart squeezing function is normal. The test can check the overall squeezing strength of the heart (ejection fraction). A normal value is above 55%.

The test also can check the motion of individual parts of the heart. If one part of the heart is moving poorly while the others move well, it may mean that there is a blockage in the artery of the heart that delivers blood to the damaged part.

What abnormal results mean:

Abnormal results may indicate:

Blockages in the coronary arteries (coronary artery disease)
Heart valve disease
Other cardiac disorders that weaken the heart function
Past heart attack (myocardial infarction)
Poor pumping function

Other conditions under which the test may be performed:

Heart, front view

MUGA test
