what the risks are --> heart, muga test, cardiac blood pooling imaging, heart scan, nuclear, radionuclide ventriculography, rnv, multiple gate acquisition scan, muga, nuclear ventriculography, test that uses radioactive materials, tracers to make heart chambers, blood vessels visible, procedure is non-invasive, heart structures, not touched by instruments, a radioactive isotope, technetium is injected into vein, radioactive isotopes attach to red blood cells, pass, the heart, in the circulating blood, radioactive isotope, traced, the heart using special cameras, scanners, images combined, an electrocardiogram, resting, tested again, exercise, after taking certain medications, you, be told not to eat, drink beverages containing caffeine, alcohol, several hours, feel a brief sting, pinch, the iv is inserted, have trouble staying still, test, how well the blood is pumping, the heart, check, clogged arteries, normal results indicate normal heart function, a normal cardiac response to exercise, abnormal results, indicate poor pumping function, a prior heart attack, myocardial infarction, blockages, in the coronary arteries, coronary artery disease, heart valve disease, cardiac disorders associated, weakening, the heart function, additional conditions under which the test performed, atrial septal defect, dilated cardiomyopathy, heart failure, idiopathic cardiomyopathy, mitral stenosis, peripartum cardiomyopathy, senile cardiac amyloid nuclear imaging tests carry a very low risk of complications, exposure, radioisotope is safe, patients undergoing, nuclear imaging test.
