摘　　要：为了估价ＣＴ对前列腺疾病诊断的价值，笔者对１２０例全部经ＣＴ检查的病例作了研究。有关前列腺大小与年龄的关系，在１２０例中其大小尽管有随年龄增长而有所增大的趋势，但均未超过正常数值范围。１２０例中３６例为前列腺癌，８４例前列腺肥大。ＣＴ表现为密度不均、结节、精囊角变钝或消失；此多见于前列腺癌，亦见于前列腺肥大。然而ＣＴ的复合征象主要见于前列腺癌，只是阳性率相对较少。重要的是ＣＴ对前列腺的良、恶性鉴别是困难的。但对病变的延伸范围及前列腺癌的分期可提供较可靠的依据。In order to evaluate CT in the differential diagnosis of prostatic diseases,120 cases were studied.Although in our series,the size of prostate increased with age,all were within the normal range,There were 36 cases of prostatic carcinoma and 84 cases of benign hypertrophy.Abnormal CT appearances of prostate such as inhomogeneous density, nodules,blunting or obliteration of seminal vesi-cle angle were more frequent in prostatic carcinoma but might also be present in hypertrophy of prostate.Combination of these CT findings was mainly found in carcinoma despite of relatively low positive rate.CT could hardly differentiate benign prostatic diseases from malignant tumors, however,CT does pro-vide useful informations as to the extent and staging of tumor.
