In order to solve the problem of scanning magnetic resonance imaging in prenatal diagnosis, the application and research of placental implantation have been proposed. Placental implantation is a serious obstetric emergency, which refers to the abnormal attachment of placental villi caused by the dysplasia of decidual basal layer. A study from the United States showed that the incidence of placental implantation in pregnant women during delivery increased from 9.9/30000 to 11.6/20000 from 2006 to 2019, which increased the risk of prenatal or postpartum hemorrhage, hysterectomy, stillbirth, abdominal organ injury, and so on. Clinically, patients can show severe prenatal or postpartum hemorrhage, postpartum placental retention, uterine perforation, and secondary infection, which may seriously endanger the lives of pregnant mothers and fetuses. Placental implantation can also have no obvious symptoms before delivery, which leads to insufficient prenatal diagnosis. Gielchinsky retrospectively studied 410 patients with placental implantation and found that only 9 patients were detected by prenatal ultrasound or magnetic resonance imaging (MRI), and the detection rate was only 6.6%. It can be seen that if the accurate diagnosis of placental implantation can be made before prenatal or symptoms appear, clinical intervention treatment can be carried out in time to reduce the probability of hysterectomy and improve the examination means of patients' prerecovery. At present, studies at home and abroad suggest that it has good clinical application value and research prospect in the clinical diagnosis of placental implantation.
为了解决产前诊断中磁共振扫描的问题，提出了胎盘植入的应用和研究。胎盘植入是一种严重的产科急症，是指由于蜕膜基底层发育不良导致胎盘绒毛异常附着。美国的一项研究表明，2006 年至 2019 年，分娩孕妇的胎盘植入发生率从 9.9/30000 增加到 11.6/20000，增加了产前或产后出血、子宫切除、死产、腹部器官损伤等风险。临床上，患者可表现为严重的产前或产后出血、产后胎盘残留、子宫穿孔和继发感染，可能严重危及孕妇和胎儿的生命。胎盘植入也可在分娩前无明显症状，导致产前诊断不足。Gielchinsky 回顾性研究了 410 例胎盘植入患者，发现仅 9 例患者通过产前超声或磁共振成像（MRI）检测到，检出率仅为 6.6%。可见，如果能在产前或症状出现前准确诊断胎盘植入，及时进行临床干预治疗，可降低子宫切除率，提高患者的预后检查手段。目前，国内外研究表明，其在胎盘植入的临床诊断中具有良好的临床应用价值和研究前景。
