摘要: 本文分析了彩色多普勒超声结合磁共振成像对胎盘植入的诊断价值。选取我院产科2016年1月~2018年6月期间收治的64例胎盘植入患者为研究对象,分别对其实施彩色多普勒超声诊断、磁共振成像诊断、彩色多普勒超声联合磁共振成像诊断,以手术结果为参照,对比3种诊断方案的符合率、敏感度、特异度、阳性预测值、阴性预测值和约登指数。手术结果证实,64例胎盘植入患者中有粘连性胎盘15例、植入性胎盘30例、穿透性胎盘19例,诊断符合率顺序为:彩色多普勒超声联合磁共振成像 > 磁共振成像 > 彩色多普勒超声,差异有统计学意义(P<0.05);3种诊断方案的敏感度、特异度、阳性预测值、阴性预测值、约登指数相比较,彩色多普勒超声联合磁共振成像 > 磁共振成像 > 彩色多普勒超声,差异有统计学意义(P<0.05)。据此可知,在进行胎盘植入诊断时,彩色多普勒超声联合磁共振成像效果更佳,不失为一种优选影像学诊断方案,值得加以推广使用。

Abstract: The diagnostic value of color Doppler ultrasound combined with magnetic resonance imaging in placenta implantation was analyzed in this study. 64 patients with placenta implants admitted to our hospital from January 2016 to June 2018 were selected as subjects. Color Doppler ultrasound 150 diagnosis, magnetic resonance imaging diagnosis, color Doppler ultrasound combined with magnetic resonance imaging diagnosis were performed. The surgical results were used as reference. The coincidence rate, sensitivity, specificity, positive predictive value, negative predictive value and Yoden index of the three diagnostic protocols were compared. Surgery results confirmed that there were 15 cases of adhesive placenta, 30 cases of implanted placenta and 19 cases of penetrating placenta in the 64 cases of placenta-implanted patients. The sequence of diagnose coincidence rate was:color Doppler ultrasound combined with magnetic resonance imaging > magnetic resonance imaging > color Doppler ultrasound, the difference was statistically significant (P<0.05). And the sequence of sensitivity, specificity, positive predictive value, negative predictive value, Yoden index of three diagnostic protocols was:color Doppler ultrasound combined with magnetic resonance imaging > magnetic Resonance imaging > color Doppler ultrasound, the difference was statistically significant (P<0.05). In conclusion, color Doppler ultrasound combined with magnetic resonance imaging is the best method in the diagnosis of placenta implantation, and it is a preferred imaging diagnosis scheme, which is worthy of popularization.
