声触诊组织量化技术在子宫肌瘤和子宫腺肌瘤鉴别中的应用

Application of virtual touch tissue quantification imaging in diagnosing of uterine hysteromyoma and adenomyoma

目的:应用声触诊组织量化技术(VTQ)探讨其在子宫肌瘤和子宫腺肌瘤鉴别中的价值。方法:对比分析42例非变性子宫肌瘤、14例变性子宫肌瘤及25例腺肌瘤病灶处血流参数及剪切波传播速度(SWV)。结果 :42例非变性子宫肌瘤SWV为(2.72±0.31)m/s;14例变性子宫肌瘤SWV为(1.88±0.25)m/s;25例子宫腺肌瘤SWV为(1.91±0.27)m/s。非变性子宫肌瘤组SWV明显高于变性子宫肌瘤组及子宫腺肌瘤组,差异有统计学意义(P<0.05)。变性子宫肌瘤组与子宫腺肌瘤组SWV比较,差异无统计学意义(P>0.05)。子宫肌瘤及子宫腺肌瘤患者阻力指数(RI)与SWV呈正相关(r=0.753,0.544,0.506,P<0.05)。结论 :VTQ能够量化反映子宫肌瘤和子宫腺肌瘤病灶处弹性硬度。

Objective To evaluate the performance of virtual touch tissue quantification imaging（VTQ）for differential diagnosing in uterine hysteromyoma and adenomyoma. Methods Blood flow parameters and SWV（shear wave velocities） from 42 regular hysteromyomas,14 abnormal hysteromyomas and 25 uterine adenomyomas were compared and analyzed through color Doppler. Results The SWV of regular hysteromyomas was on average of（2.72 ± 0.31） m / s;that of abnormal hysteromyomas（1.88 ± 0.25） m / s;while the SWV of uterine adenomyomas was on average of 1.91 ± 0.27 m / s. The mean SWV in regular hysteromyomas group was significantly higher than that in abnormal hysteromyomas group and uterine adenomyomas group（P〈0.05）.There was no significant difference of SWV between abnormal hysteromyomas group and uterine adenomyomas group（P〈0.05）.The resistance index and SWV of uterine hysteromyomas and adenomyomas had positive correlation（r = 0.753,0.544,0.506,P〈0.05）. Conclusion VTQ can quantify the stiffiness of uterine hysteromyoma and adenomyoma.
