| 目的 探讨产前MRI诊断胎儿消化道闭锁的价值。方法 回顾性分析经出生后手术证实的24胎消化道闭锁胎儿的产前MRI资料，与手术结果对照，分析胎儿消化道闭锁的产前MRI特点。结果 24胎消化道闭锁胎儿中，食管闭锁5胎，2胎Vogt分型Ⅲa型T2WI未显示胃泡，3胎Ⅲb型T2WI表现为食管上段囊状扩张，胃泡微小。十二指肠闭锁4胎，MRI均表现为"双泡征"。小肠闭锁10胎，5胎无合并症，其中1胎为空肠闭锁，T2WI示肠管信号均匀，4胎回肠闭锁T2WI示肠管呈等低混杂信号；1胎合并肠重复畸形，4胎合并胎粪性腹膜炎。1胎幽门闭锁合并回肠闭锁和结肠闭锁，T2WI示胃泡扩张。4胎肛门闭锁胎儿中，3胎低位闭锁，表现为胎粪聚集致降结肠、乙状结肠、直肠扩张，1胎中位闭锁，其结肠、乙状结肠、直肠管腔均发育细小。结论 产前MRI对诊断胎儿消化道闭锁有一定价值。 |

| Objective To explore the diagnostic value of prenatal MRI in fetal digestive tract atresia. Methods Prenatal MRI data of 24 fetuses with digestive tract atresia confirmed by postnatal surgery were retrospectively analyzed. The prenatal MRI features of fetal digestive tract atresia were observed in comparison with the surgical results. Results Among the 24 fetuses with digestive tract atresia, 5 fetuses were found with esophageal atresia, 2 were Vogt type Ⅲa, fetal stomach was not seen on T2WI, 3 were type Ⅲb, shrinkage of fetal stomach and presence of dilated pouch-like esophageal were displayed on T2WI. Duodenal atresia was noticed in 4 fetuses, and MRI showed "double bubble sign". Intestinal atresia was detected in 10 fetuses, 5 without comorbidities and 1 with jejunal atresia, T2WI showed uniform intestinal tube signal. Ileum atresia was found in 4 fetuses, and intestinal tube showed low mixed signal. One intestinal atresia fetus was found combined with intestinal duplication deformity, and 4 were found with meconium peritonitis. One fetal pyloric atresia combined with ileal atresia and colon atresia, manifested as gastric expansion on T2WI. Among the 4 fetuses with anal atresia, 3 were low-level atresia, characterized with meconium-sacral colonic sigmoid colon and rectal dilatation, and 1 fetus was median atresia, with poor developed colon, sigmoid colon and rectal lumen. Conclusion Prenatal MRI has certain value in diagnosis of fetal digestive tract atresia. |
