摘　　要：目的 探究基于磁共振成像(MRI)及扩散张量成像(DTI)双模态成像技术在盆底肌功能障碍(PFD)诊断中的临床价值。方法选取喀什地区第一人民医院收治的50例PFD患者作为研究对象并纳入PFD组,另选取同期于医院体检的30例正常志愿者作为对照,纳入对照组,两组均采用MRI及DTI双模态成像技术进行检查,比较两组患者临床资料、盆底肌扫描面积(髂骨尾骨肌、耻骨尾骨肌、耻骨直肠肌)、肛提肌裂孔宽度、盆底标志线(H线、M线)、髂骨尾骨肌厚度(ICT)、髂骨尾骨肌角(ICA)及肛提肌角(LPA),髂骨尾骨肌、耻骨直肠肌各向异性分数(FA)及表观弥散系数(ADC)值。结果两组一般资料比较在统计学上无显著性差异(P>0.05);PFD组静态与动态髂骨尾骨肌、耻骨尾骨肌、耻骨直肠肌面积均小于对照组(P<0.05);PFD组静态与动态肛提肌裂孔宽度大于对照组,H线、M线长于对照组(P<0.05);PFD组ICT少于对照组,LPA大于对照组,两组ICA比较在统计学上无显著性差异(P>0.05);两组髂骨尾骨肌、耻骨直肠肌FA、ADC值比较在统计学上无显著性差异(P>0.05)。结论基于MRI及DTI双模态成像技术可反映PFD患者盆底功能及形态变化,在PFD患者中具有良好的应用价值,可用于临床推广。Objective To investigate the clinical value of dual-modality imaging based on MRI and DTI in diagnosing PFD.Methods A total of 50 patients with PFD admitted to the First People s Hospital of Kashgar(PFD group) and 30 normal volunteers(control group) were included in the study at the same time.All subjects were examined with MRI and DTI dual-modality imaging techniques.Comparison was made between the grou ps in terms of clinical data,scan a reas of pelvic floor muscles(iliococcygeus muscle,pubococcygeal muscle and puborectal muscle),width of anal levator hiatus,pelvic floor marker lines(H line and M line),ICT,ICA,LPA,FA and ADC values of iliococcygeus muscle and puborectal muscle.Results General data of the two groups were comparable(P>0.05).Compared to control group,areas of static and dynamic iliococcygeus muscle,pubococcygeal muscle and puborectal muscle were smaller in PFD group(P<0.05).The width of static and dynamic anal levator hiatus was larger in PFD group.H line and M line were longer in PFD group(P<0.05).ICT was smaller and LPA was greater in PFD group.The two groups had similar ICA,and comparable FA and ADC values of iliococcygeus muscle and puborectal muscle(P>0.05).Conclusion Dual-modality imaging based on MRI and DTI can reflect the changes of pelvic floor function and morphology in patients with PFD.It has good application value in patients with PFD.
