剪切波弹性成像定量评价阴茎海绵体硬度
|
摘要
目的探讨实时剪切波弹性成像(SWE)定量评价阴茎海绵体硬度的价值。方法收集150名健康志愿者,根据年龄分为5～12岁组、13～18岁组、19～30岁组、31～50岁组、51～70岁组。采用SWE成像功能定量测量其阴茎海绵体的杨氏模量值。结果随年龄增大,其阴茎海绵体硬度值增加,5～12岁组为(9.05±0.85)kPa、13～18岁组为(11.01±1.34)kPa、19～30岁组为(12.03±0.85)kPa、31～50岁组为(16.33±1.56)kPa、51～70岁组为(24.46±1.81)kPa。结论 SWE技术定量测量阴茎海绵体杨氏模量值无创、简便、安全,有重要临床应用价值。
Objective To explore of value of real-time shear wave elastography(SWE) in quantitative evaluation of corpus cavernosum hardness. Methods Totally 150 healthy volunteers were divided into 5—12 years old group, 13—18 years old group, 19—30 years old group, 31—50 years old group and 51—70 years old group. Young's modulus of the corpus cavernosum was measured quantitatively with SWE imaging function. Results The hardness of penile cavernosum increased with the increase of age. Young's modulus was(9.05±0.85)kPa in 5—12 years old group,(11.01±1.34)kPa in 13—18 years old group,(12.03±0.85)kPa in 19—30 years old group,(16.33±1.56)kPa in 31—50 years old group and(24.46±1.81)kPa in 51—70 years old group. Conclusion SWE can be used for quantitative measurement of Young's modulus of corpus cavernosum, which is noninvasive, simple, safe and has important clinical application value.
