The correlation between multi-gate radionuclide cardioangiography with ^<99m>Tc-HSA and left ventricular angiography about left ventricular ejection fraction is excellent (γ=0.902) in the diagnosis of ischemic heart disease. Moreover, right ventricular ejection fraction is high precision, and its value is more dependable than cardiac catheterization by correcting the motion of tricaspid valve. The rate of coincidence between multi-gate radionuclide cardioangiography and left ventricular angiography is totally 84 percent about 7 segments of A・H・A (American Heart Association) standard on the fifty examples at the estimation of wall motion, however, it sign low value because of doubling left ventricular and right ventricular with segment 1,2,5. But it can be improved by collecting the list mode at first-pass radionuclide cardioangiography, and this way of collecting date is valuable for right ventricular infarction. The slant-collimator is valuable for the diagnosis of ischemic area by myocardio scintigraphy with ^<201>Tl.
