Effect of respiratory suspension on the computation of volume-based early peak filling rate to late peak filling rate ratio

Effect of respiratory suspension on the computation of volume-based early peak filling rate to late peak filling rate ratio

“…From these contours time-LV volume curve was further analyzed using custom-written software in MATLAB™. The raw LV volume curve was upsampled by a factor of 4, and the derivative of the time-volume curve was estimated using the method described in [3]. We defined the ratio of EPFR to LPFR as the MR equivalent surrogate of velocity based echo index of E over A ratio.…”
