Fifty-six patients admitted for surgery due to suspicion of testicular cancer were randomly selected for preoperative ultrasound scanning. The result of scanning was compared with the diagnosis obtained at surgery and subsequent microscopy. Thirty-one patients had testicular cancer which in all cases had been detected by ultrasound. In patients suffering from benign diseases a tumor of the testis was seen (1 patient) or suspected (3 patients) in 4 patients. Two of these patients had an infection of the testis, and one had the testis removed as a tumor was suspected also at surgery. The diagnostic specificity of a visualised or suspected testicular tumor seen by ultrasound was 89%, and the diagnostic sensitivity was 100%. The echo pattern of testicular tissue adjacent to testis tumors was very irregular, with a score 4 in all tumor using a score from 1 (regular) to 5 (tumor pattern). The echo pattern of the contralateral testicles was more irregular (mean score 3.3) in tumor patients compared with the echo pattern in patients suffering from benign diseases (mean score 2.7).
56名因疑似睾丸癌而入院接受手术的患者被随机选取进行术前超声扫描。将扫描结果与手术及后续显微镜检查所得到的诊断结果进行比较。31名患者患有睾丸癌，所有病例均通过超声检测到。在患有良性疾病的患者中，4名患者的睾丸发现了肿瘤（1例）或疑似肿瘤（3例）。其中2名患者患有睾丸感染，1名患者因手术时也怀疑有肿瘤而切除了睾丸。超声所见可视化或疑似睾丸肿瘤的诊断特异性为89%，诊断敏感性为100%。睾丸肿瘤相邻的睾丸组织的回声模式非常不规则，使用从1（规则）到5（肿瘤模式）的评分，所有肿瘤的评分为4分。与患有良性疾病的患者的回声模式（平均评分为2.7）相比，肿瘤患者对侧睾丸的回声模式更不规则（平均评分为3.3）。
