A study was made of 100 cadaveric prostates (71 benign glands and 29 invaded by adenocarcinoma) using a technique that enabled per-rectal ultrasonography to be carried out and their volumes measured by computed planimetry. These volumes were compared directly with the actual volumes of the glands measured after dissection from the cadaver specimens. A high degree of correlation was obtained for the measurement of benign glands (r = 0.982) and glands containing cancers confined within the capsule (r = 0.961). Estimation of the size of cancers unconfined to the gland was poor and measurement was not possible with 3 malignant prostates that had extended beyond the prostatic capsule so that the ultrasonic boundary could not be defined.
采用一种能进行直肠超声检查并通过计算机平面测量法测量前列腺体积的技术，对100个尸体前列腺标本（71个良性腺体和29个被腺癌侵犯的腺体）进行了研究。将这些体积与从尸体标本上解剖下来后测量的腺体实际体积直接进行比较。对于良性腺体的测量（r = 0.982）以及包膜内局限型癌的腺体测量（r = 0.961），均获得了高度相关性。对于超出腺体范围的癌，其大小估计不佳，且有3个恶性前列腺已超出前列腺包膜，无法确定超声边界，因而无法进行测量。
