摘　　要：①目的　探讨CT对前列腺癌和前列腺肥大的鉴别诊断价值。②方法　对经手术病理或穿刺活检证实的前列腺癌和前列腺肥大病人各 2 3例的CT征象进行回顾性分析。③结果　前列腺癌病人中出现低密度结节、形态不规则 (横轴位 )、膀胱壁浸润、膀胱内球形及精囊角变钝消失征象等的例数均高于前列腺肥大病人 ,两者比较差异均有显著性 (χ2 =5 .6 6～ 9.13,P <0 .0 5 ) ;前列腺肥大病人膀胱内出现双峰状软组织包块征象的例数高于前列腺癌病人 (χ2 =5 .2 5 ,P <0 .0 5 )。④结论　CT对前列腺癌与前列腺肥大的鉴别诊断有一定意义。Objective\ To evaluate the value of CT in differentiating prostatic carcinoma (PC) from benign prostatic hyperplasia(BPH). \ Methods\ CT features of 23 cases of PC and 23 cases of BPH were studied retrospectively. All cases were confirmed pathologically, either by surgery or needle biopsy. \ Results\ The incidence of low density nodule,irregular figure, bladder wall infiltrated, round mass in bladder and blunting or obliteration of seminal vesicle angle was more frequently seen in prostatic carcinoma, the difference being significant ( χ 2=5.66-9.13, P <0.05). The feature of double peak soft tissue mass in the bladder was more commonly seen in BPH than in PC ( χ 2=5.25, P <0.05). \ Conclusion\ CT is of certain significance in differentiating PC from BPH.
