Abstract：
This article delves into the latest MR imaging developments dedicated to diagnosing placenta accreta spectrum (PAS). PAS, characterized by abnormal placental adherence to the uterine wall, is of paramount concern owing to its association with maternal morbidity and mortality, particularly in high-risk pregnancies featuring placenta previa and prior cesarean sections. Although ultrasound (US) remains the primary screening modality, limitations have prompted heightened emphasis on MR imaging. This review underscores the utility of quantitative MR imaging, especially where US findings prove inconclusive or when maternal body habitus poses challenges, acknowledging, however, that interpreting placenta MR imaging demands specialized training for radiologists.
摘要：
本文探讨了用于诊断胎盘植入频谱（PAS）的最新MR成像技术。PAS,以胎盘对子宫壁的异常粘附为特征，由于其与孕产妇发病率和死亡率相关，特别是在以前置胎盘和先前剖宫产为特征的高危妊娠中。尽管超声（美国）仍然是主要的筛查方式，局限性促使人们更加重视MR成像.这篇综述强调了定量MR成像的实用性，特别是在美国的研究结果没有定论的情况下，或者当母亲的身体习惯构成挑战时，承认,然而,解释胎盘MR成像需要放射科医师的专业培训。
