摘要
目的 对比分析凸阵和线阵探头的声触诊弹性成像(sound touch elastography,STE)和声触诊弹性测量(sound touch quantify,STQ)技术检测女性肛提肌硬度的临床应用价值.方法 对 69 例健康体检者右侧肛提肌前、中、后 3 个部位行平静、收缩、拉伸状态下的凸阵和线阵STE、STQ检查,分析 4 项检测技术的成功率、变异度、测量值(杨氏模量)、操作者间和操作者内的一致性.结果 凸阵STE和线阵STQ技术检测肛提肌总体成功率较高、总体变异度较小,与凸阵STQ和线阵STE技术比较,差异均有统计学意义(均P<0.05).凸阵STQ技术和线阵STE技术检测的肛提肌弹性模量值差异有统计学意义(P<0.05);凸阵 STE技术和线阵 STQ技术检测的肛提肌弹性模量值差异无统计学意义(P>0.05).凸阵探头STE和线阵探头STQ技术操作者间和操作者内一致性分别为 0.869、0.919、0.772、0.850.结论 凸阵探头STE和线阵探头STQ技术检测肛提肌硬度总体成功率均较高、总体变异度小,弹性模量测值无明显差异,值得推广.
Abstract
Objective To assess the feasibility of sound touch elastography(STE)and sound touch quantify(STQ)in convex transducer and linear transducer for female levator ani muscles stiffness assessment.Methods A total of 69 healthy volunteers underwent STE and STQ examinations of the right levator ani muscles at three different locations(anterior,middle,and posterior)during rest,contraction,and stretch states.The study analyzed the success rate,variability,and measurements(Young's modulus)of the detection techniques,as well as assessed the inter-operator and intra-operator consistency.Results Both convex transducer STE and linear transducer STQ techniques exhibited higher overall success rates and lower variability in detecting the middle segment of the levator ani muscles compared to convex transducer STQ and linear transducer STE techniques,with statistically significant differences(all P<0.05).There was statistically significant difference in the measurements of levator ani muscles detected by convex transducer STQ technique and linear transducer STE technique(P<0.05).There was no statistically significant difference in the measurements of levator ani muscles detected by convex transducer STE technique and linear transducer STQ technique(P>0.05).The inter-operator and intra-operator consistency of convex transducer STE and linear transducer STQ technology were determined to be 0.869,0.919,0.772,0.850,respectively.Conclusion Both convex transducer STE and linear transducer STQ techniques demonstrate high success rates and low variability in assessing levator ani muscles stiffness,and there was no significant difference in the measurements of them,they were suitable for clinical promotion widely.
