Calculated gated lvef
WebA normal EF ranges from 55-69%, and is calculated using the following equation: Ejection fraction (EF) in percentage is defined as: EF (%) = SV/EDV x 100. Where SV: Stroke Volume and EDV: End Diastolic Volume. Ejection fraction (EF) is basically a percentage, of how much blood the left ventricle pumps out with each contraction. WebEDV, ESV and LVEF were calculated from gated SPECT using EXINI. Directly before or after SPECT, cMRI (20 gates cardiac per cycle) was performed. EDV, ESV and LVEF were calculated using Simpson's rule. Perfusion defects were quantified using the summed-rest-score (SRS). Total number of myocardial counts were used to rate image quality.
