Abstract:
Placenta accreta spectrum(PAS)refers to a condition where placental villi abnormally adhere to or invade the uterine muscle layer to varying degrees.PAS can lead to severe obstetric complications,including postpartum hemorrhage,hysterectomy and even life-threatening situations.Nowadays,the diagnosis of PAS typi-cally relies on imaging examinations such as ultrasound.Despite the widespread use of ultrasound,its accuracy is a subject of controversy,leading to the emergence of new imaging prenatal diagnostic indicators.This article aims to review prenatal diagnostic indicators of PAS,including ultrasound features and magnetic resonance imaging(MRI).Additionally,we will discuss existing joint diagnostic methods and the latest research findings.
