To determine the effect of magnetic resonance (MR) imaging findings on management of complex fetal disorders.
MR imaging of the fetus was performed in 25 consecutive pregnant patients referred because of possible complex fetal disorders suspected on the basis of ultrasonographic (US) findings. Spoiled gradient-echo and single-shot rapid acquisition with relaxation enhancement MR imaging were performed in multiple planes anatomic to the fetus during maternal breath holding.
In the fetuses in 24 of 25 women, MR studies were technically satisfactory. MR imaging directly influenced fetal care in four (17%) of 24 cases by demonstrating congenital high airway obstruction syndrome, congenital hemochromatosis, unilateral cerebellar deficiency in association with congenital diaphragmatic hernia, and severe facial disfigurement due to a giant anterior neck mass. In eight (33%) cases, MR imaging provided supplementary findings, but did not affect fetal care. In 12 (50%) cases, MR imaging results confirmed US findings.
In cases of complex fetal disorders, MR imaging results can be used to supplement or confirm US findings and may directly affect management.
确定磁共振（MR）成像结果对复杂胎儿疾病管理的影响。
对25例因超声（US）检查发现可疑复杂胎儿疾病而转诊的连续妊娠患者进行胎儿MR成像检查。在孕妇屏气期间，在胎儿的多个解剖平面上进行扰相梯度回波和单次激发快速采集弛豫增强MR成像。
25例孕妇中24例胎儿的MR检查在技术上令人满意。MR成像通过显示先天性高气道梗阻综合征、先天性血色素沉着症、与先天性膈疝相关的单侧小脑发育不全以及巨大颈部前肿块导致的严重面部畸形，直接影响了24例中的4例（17%）胎儿的治疗。在8例（33%）病例中，MR成像提供了补充性发现，但未影响胎儿治疗。在12例（50%）病例中，MR成像结果证实了US检查结果。
在复杂胎儿疾病病例中，MR成像结果可用于补充或证实US检查结果，并可能直接影响治疗管理。
