摘要
近年来,MRI超快速扫描技术不断发展,部分解决了胎动伪影的难题,使MRI在胎儿及胎盘检查中的优势突显,目前已成为超声诊断胎儿及胎盘异常的有力补充。MR T2WI在观察胎盘结构方面具有明显的优势,DWI、MRS等功能成像亦可用于胎盘功能评价,多种MRI扫描技术联合应用可为临床提供更清晰、直观的影像学资料。本文主要对目前MRI评价胎盘功能的临床应用进展进行综述。
Recently,the development of MRI rapid-scan technology has been helpful in reducing fetal movement artifacts.With multiplanar imaging capability and superior soft tissue contrast,MRI shows significant advantages in fetal and placental examination.It has been a strong supplement for ultrasound diagnosis of abnormal fetus and placenta.MR T2 WI has extraordinary advantages in placenta structure observation.Functional imaging can be used in placenta functional evaluation.The combination of multiple MRI technologies can provide clearer and more visualized images for clinical diagnosis.The progresses of MRI in evaluating placental function for clinical use were reviewed in this article.
