【摘要】 目的：探讨ＣＴ对前列腺癌的诊断价值。方法：收集１９８６～１９９７年经前列腺穿刺活检或手术病理证实为前列腺癌的２２例进行ＣＴ回顾性分析。结果：前列腺癌组织在前列腺包膜内生长及突破包膜向外生长各１１例，ＣＴ见肿瘤多呈不规则低密度或混杂密度灶，增强后病灶显示更为清晰；局限于包膜内的癌组织以类圆形、结节形为主，突破包膜向外生长的癌组织以不规则形为主，并易向周围组织侵犯生长，其中侵犯膀胱的可见沿膀胱壁呈蔓状或包埋状生长。结论：ＣＴ在前列腺癌的诊断中占有重要地位。它能发现和显示病变，确定病变侵犯范围，了解是否有远隔脏器转移，对确定肿瘤术前分期、选择治疗方案及判定预后起着重要作用。更多还原

【Abstract】 Objective: To explore CT diagnostic value of prostate carcinoma. Methods: CT features of 22 cases of prostate carcinoma confirmed by prostate puncture biopsy or surgery and pathology were analyzed retrospectively. Results: The lesions of tumors were limited within prostate and out of prostate in 11 cases respectively,the former often appeared as cycloid and nodular,the latter often appeared as irregular with invasion of adjacent tissue or metastasis of remote organs.The lesions were often hypodensity or mixture-density and became more clear on contrast enhanced scans. Conclusion: CT can detect most prostate carcinoma and show the location,size and range of lesions,CT plays an important role in confirming preoperative stage,selecting the therapeatic plans and evaluating the prognosis of prostatic carcinoma.更多还原
