Ultrasonographic characteristics of the uterine lesion in ETT, PSTT and IM/CC.

*Color score 1∼4 stand for the semi-quantitative Doppler signal from absence to abundant. ΔPSV, peak systolic velocity; EDV, end diastolic velocity; RI, resistance index; S/D, systolic/diastolic flow velocity ratio. Continuous values are shown in the format of “mean (range)”, and counting data are shown in the format of contingency table. §p-value between ETT and PSTT is less than 0.05. ¶p-value between ETT and IM/CC is less than 0.05.
