目的:利用实时剪切波弹性成像(shear wave elastography, SWE)定量分析不同睾酮水平阴茎组织硬度之间的差异。方法:睾
酮水平不同SD 大鼠两组,低睾酮水平组(1 月龄,睾酮水平1.00~1.50 ng/mL,n=10)和高睾酮水平组(13月龄,睾酮水平2.00~2.50
ng/mL,n=10)。采用放射免疫法测定各组大鼠血清睾酮水平。选用法国SuperSonic Imagine 公司生产的Aixplorer超声诊断仪,启
动SWE 模式对阴茎进行SWE 成像并测量其剪切波硬度(shear wave stiffness, SWS)。分析比较两组大鼠血清睾酮水平之间的差

Objective:To quantitatively analyze the differences of penis stiffness with different levels of testosterone using shear
wave elastography (SWE).Methods:Two groups of SD rats with different levels of testosterone: the low testosterone group (1 month,
testosterone 1.00~1.50 ng/mL, n=10) and the high testosterone group (13 month, testosterone 2.00~2.50 ng/mL, n=10). The
radioimmunoassay was used to measure the level of testosterone and the ultrasound device Aixplorer (SuperSonic Imagine,
Aix-en-Provence, France) was used for the SWE imaging and SWS measurement of penis. The differences of the level of testosterone
between the two groups and SWS between the two groups were analyzed.Results:The level of testosterone and SWS of penis were all
successfully measured. The level of testosterone of the two groups was respectively (1.30± 0.16) ng/mL and (2.29± 0.14) ng/mL, there
were significant differences of the level of testosterone between the two groups (P<0.01). The penis SWS of the two groups was
respectively (9.86± 0.72) kPa and (7.80± 1.43) kPa, there were significant differences of penis SWS between the two groups (P<0.01).Conclusion:The differences of penis stiffness with different levels of testosterone can be detected using SWE. Therefore, SWE maybe
serve as a potential noninvasive method of evaluating the penis stiffness. |
