摘　　要：目的初步探讨声触诊弹性成像(STE)和声触诊弹性测量(STQ)两种弹性成像技术在测量正常成人睾丸硬度中应用的可行性,并对两种技术在正常睾丸中的应用进行比较。方法采用STE和STQ分别对12例正常成年男性的双侧睾丸进行横断面及纵断面硬度值的测量和比较。结果STE和STQ测量正常睾丸硬度的组间及组内一致性都非常好。在纵断面上,左右睾丸的STE硬度值分别为(16.28±5.03)kPa和(15.72±3.70)kPa,STQ硬度值分别为(17.07±7.52)kPa和(16.08±6.10)kPa;在横断面上,左右睾丸的STE硬度值分别为(13.49±4.19)kPa和(13.14±3.81)kPa,STQ硬度值分别为(13.29±6.16)kPa和(11.71±4.87)kPa。同种技术测量不同断面的睾丸硬度值之间差异有统计学意义(P<0.05),其中以STE测量纵断面硬度值的变异系数最小,为27.07%。结论STE和STQ在测量睾丸硬度中均不易受操作者的影响,其中以STE在纵断面对睾丸硬度进行测量的稳定性最好,可能更适用于睾丸硬度的检测。Objective To discuss the feasibility and consistency of sound touch elastography(STE)and sound touch quantification(STQ)in measuring normal testicular stiffness in adults,and to compare the application of these two techniques in normal testis.Methods The testicular stiffness was measured by STE and STQ in 12 normal adult males.The stiffness values of testis measured by STE and STQ were compared.Results STE and STQ of normal testicular stiffness were consistent between and within groups.In the longitudinal section,the STE and STQ values of the left and right testis were(16.28±5.03)kPa vs.(17.07±7.52)kPa and(15.72±3.70)kPa vs.(16.08±6.10)kPa,respectively.In the transverse section,the STE and STQ values of the left and right testes were(13.49±4.19)kPa vs.(13.29±6.16)kPa and(13.14±3.81)kPa vs.(11.71±4.87)kPa,respectively.The stiffness values of testes measured by the same technique at different sections showed statistically significant differences(P<0.05),and the variation coefficient of hardness values measured by STE in longitudinal section was the lowest(27.07%).Conclusion STE and STQ are not susceptible to operator's influence in testicular stiffness measurement.STE has the best stability in vertical section measurement of testicular hardness,which may be more suitable for testing testicular hardness.
