Ultrasonography of the prostate furnishes images which still cannot be fully interpreted morphologically. In a cadaver study, the ultrasound images of two groups (21 and 19) prostates, obtained in a water bath, were compared with histology slides taken at corresponding levels. In the first part of the study, using a 4 MHz probe, there was a correlation between hyperechoic lesions and stone formations in 9 out of 15 cases. A relation between hypoechoic lesions and the existence of a carcinoma could also be established in 4 out of 12 cases. In the second part of the study, using a 7 MHz probe, there was a correlation between hyperechoic lesions and stone formations in all cases. Hypoechoic lesions correlated with the presence of a carcinoma in 1 out of 8 cases. The technique used appears to be well suited for the comparative study of ultrasound images and histology. Application of the 7 MHz probe is preferable as, because of a better resolution, smaller lesions can be detected. The results of this study are not very encouraging for the use of transrectal ultrasound for the detection of small prostatic carcinomas.
前列腺超声检查所提供的图像在形态学上仍无法得到充分解读。在一项尸体研究中，将在水浴中获取的两组前列腺（分别为21个和19个）的超声图像与相应层面的组织学切片进行了比较。在研究的第一部分，使用4兆赫探头时，15例中有9例高回声病变与结石形成之间存在相关性。12例中有4例低回声病变与癌的存在之间也能确立关联。在研究的第二部分，使用7兆赫探头时，所有病例中高回声病变与结石形成之间均存在相关性。8例中有1例低回声病变与癌的存在相关。所采用的技术似乎非常适合超声图像与组织学的对比研究。由于分辨率更高，能够检测到更小的病变，因此使用7兆赫探头更佳。本研究结果对于经直肠超声用于检测小前列腺癌来说并不十分令人鼓舞。
