Trajectory of Left Ventricular True Endocardial Edge on E.C.G.- gated Planar Myocardial Perfusion Scintigraphy: Geometric and Kinematic Implications in Nuclear Cardiac Imaging

摘要

From rigorous theoretical and phantom studies it was found that true left ventricular endocardial edge coincides with circumferential trajectory of radioactive count rate maxima of a planar gated myocardial perfusion scintigram. This should invoke a renewed interest in extracting geometric and kinematic information from Nuclear (scintigraphic) images of the myocardium, as evidenced by preliminary clinical studies.
