【摘要】：目的：研究正常睾丸组织超声弹性成像声像图的特点，比较双侧睾丸实质应变率的差异。探讨病变睾丸组织超声弹性成像声像图的特点，通过比较病变睾丸组织与正常睾丸组织超声弹性成像声像图特点的差异，进一步提高睾丸疾病的诊断率及其准确性。方法：对40例正常睾丸行常规超声检查，记录下睾丸的大小、实质回声及血供情况，然后行超声弹性成像检查，，观察睾丸超声弹性成像声像图特点；测量双侧睾丸实质区域的应变率。对14例病变的睾丸同样先行常规超声检查，记录下睾丸的大小、实质回声及血供情况。然后，观察病变睾丸超声弹性成像声像图特点；评估病变睾丸病变区域的弹性得分。比较正常睾丸组织与病变睾丸组织超声弹性成像声像图的差异，进一步归纳、总结病变睾丸的超声弹性成像声像图特点。结果：（1）正常睾丸超声弹性成像声像图表现为实质中心区域以绿色为主，而边缘区域则以蓝色为主，并且在睾丸实质周边可见红色周边带；中心区域与边缘区域的应变率比值约为0.56±0.12；双侧睾丸的应变率未见明显差异。(2)超声弹性成像能反映睾丸病变组织的相对软硬度，不同病因的病灶有着各自的弹性成像特点。结论：超声弹性成像技术可以评估睾丸组织的相对硬度，虽然异常组仅有部分病种，但超声弹性成像在这些病种中的应用，也为超声对睾丸疾病的诊断及鉴别诊断提供了新方法。
[Abstract]:Objective: to study the characteristics of ultrasonic elastic imaging (EUS) of normal testicular tissue, and to compare the difference of the strain rate of the bilateral testis, and to explore the characteristics of the ultrasonic elastic imaging (EUS) of the diseased testicular tissue. In order to improve the diagnostic rate and accuracy of testicular diseases, the sonographic characteristics of ultrasonic elastic imaging were compared between the diseased testis and normal testicular tissues. Methods: 40 cases of normal testis were examined by conventional ultrasonography. The size of testis, echo of parenchyma and blood supply were recorded. The strain rate of bilateral testicular parenchyma was measured. The size of testis, echo of parenchyma and blood supply were recorded by conventional ultrasonography in 14 cases of testicular lesions. Then, the ultrasonographic characteristics of the affected testis were observed. To evaluate the elastic score of the diseased testis, to compare the difference between the normal testicular tissue and the diseased testicular tissue, and to sum up the characteristics of the ultrasonic elastic imaging sonogram of the diseased testis. Results (1) normal testicular sonography showed that the central region of the parenchyma was mainly green, while the marginal region was mainly blue, and the red peripheral zone was seen around the testis parenchyma. The ratio of strain rate between the central region and the marginal region was about 0.56 卤0.12; there was no significant difference in the strain rate of bilateral testis. The ultrasonic elastic imaging could reflect the relative soft and hard degree of testicular lesions, and the lesions with different etiology had their own characteristics of elastic imaging. Conclusion: ultrasonic elastic imaging can be used to evaluate the relative hardness of testicular tissue. Although there are only some diseases in abnormal group, the application of ultrasonic elastic imaging in these diseases. It also provides a new method for the diagnosis and differential diagnosis of testicular diseases.
