BACKGROUND This study aimed to assess the utility of magnetic resonance imaging (MRI) in the diagnosis of prenatal non-visualization of the fetal gallbladder (PNVGB). MATERIAL AND METHODS The clinical data of 32 pregnant women with PNVGB who underwent MRI examination during the second and third trimester of pregnancy were collected and their outcomes were analyzed. RESULTS MRI showed that 26 patients (81.3%) had isolated PNVGB and 6 (18.8%) had additional malformations. In 26 patients with isolated PNVGB, 7 were found in the gallbladder on MRI and 4 were found on subsequent ultrasonography. One patient had termination of pregnancy (TOP) and 1 patient was lost to follow-up; the remaining 24 patients were known to deliver a healthy child. Among the 6 patients with additional malformations, 3 terminated their pregnancies due to combined severe abnormalities: 1 patient with horseshoe kidney and 1 with fetal echogenic bowel both had a healthy child, while 1 with fetal growth restriction (FGR) delivered a child who walked on tiptoe. CONCLUSIONS MRI contributes to identifying PNVGB detected or suspected by ultrasonography.
背景 本研究旨在评估磁共振成像（MRI）在产前胎儿胆囊未显影（PNVGB）诊断中的应用价值。材料与方法 收集32例在妊娠中晚期接受MRI检查的PNVGB孕妇的临床资料，并分析其结局。结果 MRI显示，26例患者（81.3%）为孤立性PNVGB，6例（18.8%）合并其他畸形。在26例孤立性PNVGB患者中，MRI发现7例胆囊存在问题，后续超声检查发现4例。1例患者终止妊娠（TOP），1例失访；其余24例患者已知分娩出健康婴儿。在6例合并其他畸形的患者中，3例因合并严重异常而终止妊娠：1例马蹄肾患者和1例胎儿肠管回声增强患者均分娩出健康婴儿，而1例胎儿生长受限（FGR）患者分娩出踮脚走路的婴儿。结论 MRI有助于识别超声检查发现或怀疑的PNVGB。
