To compare the ability of magnetic resonance imaging (MRI) and transvaginal ultrasound (TV-US) with that of hysterosalpingography (HSG) in detecting uterine abnormalities caused by in utero diethylstilbestrol (DES) exposure.
The study was a prospective MRI and TV-US blind comparison of DES-exposed and nonexposed subjects who had had previous HSG for infertility evaluation.
MRI identified uterine constrictions in 60% of patients and T-shaped uteri in 25% of DES-exposed patients with HSG-confirmed abnormalities. TV-US did not identify uterine constrictions or T-shaped uteri in DES-exposed patients.
HSG must still be considered the preferred method in evaluating DES-related uterine abnormalities. HSG-defined uterine abnormalities associated with in utero DES exposure were variably identified by MRI and not at all by TV-US.
比较磁共振成像（MRI）和经阴道超声（TV-US）与子宫输卵管造影（HSG）检测宫内己烯雌酚（DES）暴露所致子宫异常的能力。
本研究是一项对因不孕症接受过HSG检查的DES暴露和未暴露受试者进行的前瞻性MRI和TV-US盲法比较。
在HSG确诊有异常的DES暴露患者中，MRI识别出60%的患者有子宫狭窄，25%的患者有T形子宫。TV-US未识别出DES暴露患者的子宫狭窄或T形子宫。
在评估与DES相关的子宫异常时，HSG仍应被视为首选方法。MRI对与宫内DES暴露相关的HSG定义的子宫异常识别情况不一，而TV-US则完全无法识别。
