In this prospective study a comparison of 4-versus 7-MHz transrectal ultrasonography for the detection of prostatic carcinoma is reported. A total of 150 prostates were biopsied due to suspicion of malignancy arising at either digital rectal examination, 4- and/or 7-MHz transrectal ultrasonography, or elevated serum prostate-specific antigen levels. Malignancies of the prostate were detected in 68 of the 147 eligible biopsy core specimens. The results show only marginal differences in the sensitivity, specificity, and predictive values for the two transducers.
在这项前瞻性研究中，报告了比较4兆赫与7兆赫经直肠超声检查对前列腺癌的检测情况。共有150例前列腺因怀疑在直肠指检、4兆赫和/或7兆赫经直肠超声检查时出现恶性病变或血清前列腺特异性抗原水平升高而接受活检。在147例符合条件的活检核心标本中，有68例检测出前列腺恶性肿瘤。结果显示，两种探头在敏感性、特异性和预测值方面仅有微小差异。
