normal values of left ventricular functional indices in gated 99mtc-mibi myocardial perfusion spect

introduction: although left ventricular(lv) function parameters measured by gated myocardial perfusion spect (gspect) have been validated, experimental data have revealed that the calculated the lv function parameters using gspect are affected by patient populations as well as particular acquisition and processing conditions. we tried to determine the normal values of gspect in an iranian population.  methods:  we studied 3500 iranian patients who underwent gspect in an outpatient setting. to develop normal limits of lv functional indices using gspect, 148 patients with a low (55 & lvef77, esv> 26 and lvef
