电影磁共振成像技术与经会阴超声在盆腔器官脱垂诊断评估中的应用价值

Application Value of Cine Magnetic Resonance Imaging and Transperineal Ultrasonography in the Diagnosis and Evaluation of Pelvic Organ Prolapse

目的 对比分析电影磁共振成像技术(cine-MRI)和经会阴盆底超声(TLUS)在诊断评估盆腔器官脱垂(POP)程度的应用价值。方法 纳入经盆腔器官脱垂定量(POP-Q)分度法诊断的73例POP患者为研究对象,所有患者均行cine-MRI和TLUS检查,测量并分析静息状态和最大Valsalva动作状态下的影像数据,探讨cine-MRI和TLUS检查评估POP分期的效能。结果 阴道壁上各解剖标点至处女膜缘距离与cine-MRI、TLUS各参考点至参考线的距离呈正相关(均P<0.05);cine-MRI、TLUS与POP-Q诊断前、中POP的一致性均良好(均Kappa>0.60,P<0.01),而后POP一致性较差(P<0.01)。结论 cine-MRI和TLUS能有效评定POP分级,其中在诊断后POP可优先选择cine-MRI,可为临床提供可靠的诊断依据。

Objective To compare the application value of cine magnetic resonance imaging(cine-MRI)and transperineal ultrasonography(TLUS)in the diagnosis and evaluation of pelvic organ prolapse(POP).Methods 73 subjects diagnosed as POP by pelvic organ prolapse quantification(POP-Q)were enrolled and examined by cine-MRI and TLUS respectively.In order to evaluate the diagnostic efficiency of cine-MRI and TLUS,image data acquired at rest and maximal Valsalva maneuver were observed and analyzed.Results The distances from each anatomical landmarks on the vaginal wall to the marginal hymen were positively correlated with the vertical distance from each reference point of cine MRI and TLUS to the reference line(P<0.05),cine-MRI vs POP-Q and TLUS vs POP-Q had a great consistency in the diagnosing the grading of anterior and middle pelvic cavity(P<0.05)but poor in the posterior pelvic cavity(P<0.001).Conclusion CineMRI scan and TLUS examination can evaluate the grading of POP,meanwhile,cine-MRI scan can be used as a priority auxiliary diagnostic tool for posterior pelvic cavity,which can provide a reliable diagnostic?evidence for the clinical work.
