Using linear-array transrectal prostate sonography, malignant lesions in 43 patients and benign lesions in 74 patients were evaluated. Prostate sonography was sensitive to textural changes produced by both benign and malignant diseases. However, there was considerable overlap in the sonographic appearances of benign and malignant lesions, and there were no sonographic features that reliably predicted malignancy. Hyperechoic areas were present in 58% of the carcinomas, while 19% were purely hypoechoic. Lesions containing hypoechoic foci that were posterior or posterolateral had a high incidence of cancer. The results confirm the need to biopsy all suspicious palpable lesions of the prostate.
采用线阵经直肠前列腺超声检查，对43例恶性病变患者和74例良性病变患者进行了评估。前列腺超声对良性和恶性疾病所产生的纹理变化均敏感。然而，良性和恶性病变的超声表现有相当大的重叠，且没有可靠预测恶性肿瘤的超声特征。58%的癌灶存在高回声区，而19%为纯低回声。含有位于后方或后外侧低回声灶的病变，癌症发生率较高。结果证实，有必要对所有可触及的可疑前列腺病变进行活检。
