| 目的 评估超声征象评分法联合磁共振成像（MRI）用于凶险性前置胎盘合并胎盘植入诊断中的效果，以指导临床合理诊治。方法 选择2018年3月至2019年4月就诊于我院的疑似为凶险性前置胎盘合并胎盘植入患者80例，术前均接受超声征象评分法、MRI诊断，以术后病理学结果作为金标准，评估超声征象评分法、MRI二者单一及联合诊断凶险性前置胎盘合并胎盘植入的效能，并分析植入型、非植入型的MRI影像学特征、产前超声征象评分差异。结果 80例疑似为凶险性前置胎盘合并胎盘植入患者经病理学确诊52例为植入型，28例为非植入型；植入型产前超声征象评分为（4.12±0.32）分，比非植入型的（0.38±0.11）分高，差异有统计学意义（P＜0.05）；相比非植入型，植入型的胎盘内信号不均、T2低信号带、胎盘内血管影、子宫局部外凸、胎盘子肌层分界不均比例均较高，差异有统计学意义（P＜0.05）；以病理学结果为金标准，超声征象评分法+MRI诊断凶险性前置胎盘合并胎盘植入的灵敏度（92.31%）、准确度（82.50%）均比二者单一检测高，差异有统计学意义（P＜0.05）。结论 超声征象评分法联合MRI用于凶险性前置胎盘合并胎盘植入诊断中具有灵敏度高、准确度高的优势，可评估疾病凶险程度，为临床诊疗提供较准确的参考依据。 |

| Objective To evaluate the effect of ultrasound sign scoring combined with magnetic resonance imaging (MRI) in the diagnosis of dangerous placenta previa combined with placental implantation to guide the clinical diagnosis and treatment. Methods Eighty patients with suspected dangerous placenta previa combined with placental implantation who were treated in our hospital from March 2018 to April 2019 were selected. All patients received ultrasound sign scoring and MRI diagnosis before surgery. The postoperative pathological results were used as The gold standard, to evaluate the effectiveness of ultrasound sign scoring, MRI single and combined diagnosis of dangerous placenta previa combined with placental implantation, and to analyze the differences between implantable and non-implantable MRI imaging features and prenatal ultrasound sign scores . Results Eighty patients with suspected dangerous placenta previa combined with placental implantation were diagnosed by pathology. 52 cases were implanted and 28 were non-implanted. The score of implanted prenatal ultrasound signs was (4.12 ± 0.32) points. Compared with the non-implanted type (0.38 ± 0.11), the difference was statistically significant (P <0.05); compared with the non-implanted type, the implanted placental signal unevenness, T2 low signal band, and placental blood vessels The proportions of shadow, partial uterine bulge, and uneven division of muscular layer of placental plate are higher, the difference is statistically significant (P <0.05); pathological results are used as the gold standard, ultrasound sign score method + MRI is used to diagnose dangerous placenta The sensitivity (92.31%) and accuracy (82.50%) of the combined placenta implantation were higher than the single detection of the two, and the difference was statistically significant (P <0.05). Conclusion Ultrasound sign scoring combined with MRI has the advantages of high sensitivity and high accuracy in the diagnosis of dangerous placenta previa combined with placenta implantation. It can assess the degree of disease risk and provide a more accurate reference for clinical diagnosis and treatment. |
