Antenatal recognition of severe cases of congenital diaphragmatic hernia (CDH) by ultrasound (US) and magnetic resonance imaging (MRI) may aid decisions regarding the indication of fetal endoscopic tracheal occlusion.
An integrative review was performed. Searches in MEDLINE and EMBASE used terms related to CDH, diagnosis, MRI, and US. The inclusion criteria were reviews and guidelines approaching US and MRI markers of severity of CDH published in English in the past 10 years.
The search retrieved 712 studies, out of which 17 publications were included. The US parameters were stomach and liver positions, lung-to-head ratio (LHR), observed/expected LHR (o/e LHR), and quantitative lung index. The MRI parameters were total fetal lung volume (TFLV), observed/expected TFLV, relative fetal or percent predicted lung volumes, liver intrathoracic ratio, and modified McGoon index. None of the parameters was reported to be superior to the others.
The most mentioned parameters were o/e LHR, LHR, liver position, o/e TFLV, and TFLV.
产前超声（US）和磁共振成像（MRI）对先天性膈疝（CDH）严重程度的识别，可能有助于决定胎儿内镜气管阻塞的适应证。
进行综合回顾。在 MEDLINE 和 EMBASE 中使用与 CDH、诊断、MRI 和 US 相关的术语进行检索。纳入标准为过去 10 年中以英文发表的关于 CDH 严重程度的 US 和 MRI 标志物的综述和指南。
检索到 712 项研究，其中 17 项研究被纳入。US 参数包括胃和肝脏位置、肺头比（LHR）、观察到的/预期的 LHR（o/e LHR）和定量肺指数。MRI 参数包括总胎儿肺容积（TFLV）、观察到的/预期的 TFLV、相对胎儿或百分比预测肺容积、肝脏胸腔内比率和改良 McGoon 指数。没有一个参数被报道优于其他参数。
最常提到的参数是 o/e LHR、LHR、肝脏位置、o/e TFLV 和 TFLV。
