经直肠超声实时剪切波弹性成像技术在精囊炎中的诊断价值

目的应用经直肠超声实时剪切波弹性成像技术(SWE)定量评价精囊炎精囊腺,探讨其定量参数在精囊炎中的诊断价值。方法回顾于我院行经直肠精囊腺超声SWE患者199例,精囊炎者122例,健康人77例,分别对两组精囊腺杨氏模量值进行分析,并建立ROC曲线,观察其最佳诊断效能及炎性精囊短径对其影响。结果两组Emean、Emin、Emax均有统计学意义(P<0.05),Esd无统计学意义(P>0.05)。Emean曲线下面积最大,Emean=12.05kPa时,灵敏度及特异度分别为64.9%、72.1%。炎性精囊短径及年龄与Emean无相关性(r=0.082、P=0.199,r=-0.089、P=0.164)。结论Emean、Emin、Emax在正常与精囊炎中具有诊断意义,Emean的诊断效能最高,精囊短径及年龄不是影响精囊炎精囊腺杨氏模量值改变的因素。

Differential Diagnostic Value in Seminal Vesiculitis by Transrectal Ultrasound Real-time Shear Wave Elastography

Objective To investigate the diagnostic value of the quantitative parameters of real-time shear wave elastography(SWE)in differentiating seminal vesiculitis and normal seminal vesicle,and SWE was used to obtain the parameters of semimal vesicle.Methods A total of 199patients were included,the final status of the 199patients was normal seminal vesicle in 122and seminal vesicles in 77.All seminal vesicles were underwent SWE in our department between.The parameters of optimal cut-off values were calculated by using AUC.Compare whether the short diameter of seminal vesicle and age will affect the best diagnostic efficiency of Young′s modulus.Results Emean,Emax and Emin were higher in seminal vesiculitis than normal seminal vesicles(P<0.05),the difference of Esd wasn′t significant(P>0.05).Emean with the optimal cut-off value set at 12.05kPa,showing a diagnostic sensitivity and a specificity of 64.9%,72.1%.Emean wasn′t correlated with short diameter of seminal vesible and age(r=0.082,P=0.199;r=-0.089,P=0.164).Conclusions The mean,min and max of Young′s modulus had diagnostic performances in differentiating seminal vesiculitis and seminal vesicles.Emean is most effective.The short diameter of the seminal vesicle and age aren′t a factor affecting the change of Young′s modulus of seminal vesicle in seminal vesicle.
