Analysis of the early blood kinetics of 99mTc-GSA and its verification: new one-compartment model and regression equation.

abstract：OBJECTIVE:The recent introduction of high-efficiency solid-state gamma cameras for myocardial perfusion single photon emission computed tomography has enabled lower patient radiation dose, faster imaging, and improved image quality. However, artifacts still complicate interpretation. Prone imaging is a common maneuver ...
