Figure 5 A, There was a close correlation between the RV/LV count ratio and RV visual score. Note that there were significant differences in the RV/LV count ratio among RV scores. There were significant differences in the RV/LV count ratio (B) and in RV score (C) between segments with and those without RV asynergy. The overall sensitivity and specificity of scintigraphic determination by using the lower scores 0 and 1 for detecting RV asynergy were 76.1% (35 of 46 segments) and 76.6% (49 of 64), respectively (C). The solid circles, open circles and open squares indicate organic RVT, idiopathic RVT and control subjects, respectively.
