Twenty radical prostatectomy specimens were scanned ultrasonically in vitro using a transrectal ultrasonic probe to evaluate the ultrasonic pattern of prostatic cancer. Histological and ultrasonic findings of the same areas were compared. No ultrasonic pattern specific for intracapsular prostatic cancer was found. Most often (in 40% of cases) the areas of prostatic cancer appeared hypoechoic on the ultrasonograms. In 30% of cases the carcinoma had a hyperechoic or mixed ultrasonic pattern, and in 30% the echo structure of the prostate was fairly uniform; intracapsular cancer could not be detected ultrasonically in these latter cases. The lack of a specific ultrasonic pattern for intracapsular prostatic carcinoma reduces the value of transrectal ultrasonography in detecting early intracapsular cancers. The main value of ultrasonography in patients with prostatic cancer is in the preoperative staging of the disease and in the follow-up of patients.
使用经直肠超声探头对20个根治性前列腺切除术标本进行体外超声扫描，以评估前列腺癌的超声图像。比较相同区域的组织学和超声检查结果。未发现包膜内前列腺癌的特异性超声图像。在大多数情况下（40%的病例），前列腺癌区域在超声图上表现为低回声。30%的病例中，癌具有高回声或混合超声图像，30%的病例中前列腺的回声结构相当均匀；在后一种情况下，无法通过超声检测到包膜内癌。包膜内前列腺癌缺乏特异性超声图像降低了经直肠超声检查在检测早期包膜内癌方面的价值。超声检查在前列腺癌患者中的主要价值在于疾病的术前分期和患者的随访。
