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。
Objective: To investigate the diagnostic value of CT in prostate cancer. Methods: A retrospective analysis was performed on 22 cases with prostate cancer confirmed by prostate biopsy or surgical pathology from 1986 to 1997. Results: Prostate cancer tissue grew in the capsule of the prostate and broke out the outward growth of the capsule in 11 cases. The tumors in the CT showed mostly irregular low-density or mixed densities, and the lesion showed more clearly after enhancement. The confinement in the capsule Cancer-like round, nodular-shaped, outbreaks of cancer outbreak of the cancer mainly irregular shape, and easily infringement of growth to the surrounding tissue, including the invasion of the bladder can be seen along the bladder wall was a race or bag Buried growth. Conclusion: CT plays an important role in the diagnosis of prostate cancer. It can detect and display the lesion, determine the extent of lesion invasion, and understand whether there is distant organ metastasis. It plays an important role in determining the preoperative staging of tumor, selecting the treatment plan and prognosis.
