总结了38例妊娠子宫局限性收缩的超声诊断资料,与妊娠合并子宫肌壁间肌瘤超声图像进行对照分析。结果妊娠期子宫收缩处可见圆形或椭圆形等回声团,无包膜,分界不清,内部回声光点增粗均匀,血流阻力指数(RI)0.74～1.04。妊娠合并子宫肌壁间肌瘤者肌壁间包块大多有包膜,分界清,内低回声或螺旋状低回声,血流阻力指数(RI)0.40～0.61,动态观察时图像不消失。超声图像可在形态、包膜、回声、血流、动态变化方面对两者进行鉴别诊断。
Summarized 38 cases of uterine confinement ultrasound contractility diagnostic data, and pregnant women with intrauterine myometrial ultrasound image contrast analysis. Results The uterine contractions in pregnancy showed round or oval echoes, no envelope, unclear boundaries, internal echo spot thickening, blood flow resistance index (RI) 0.74 ~ 1.04. Most of myocutaneous myomectomy in pregnancy with intramural mass encasement, clear boundaries, hypoechoic or spiral hypoechoic, blood flow resistance index (RI) 0.40 ~ 0.61, the dynamic observation of the image does not disappear. Ultrasound images can be in the shape, envelope, echo, blood flow, dynamic changes in both the differential diagnosis.
