目的：对比前列腺增生与前列腺癌的CT表现，提高两者诊断的准确性。材料与方法：收集1986－1997年经前列腺穿刺活检或手术病理证实的23例前列腺增生及22例前列腺癌进行CT回顾性分析。结果：经统计学处理，两者形状。密度、膀胱壁增厚的P值＜0．01，钙化P值＞0.05。此外前列腺癌尚可出现邻近器官的侵犯及转移征象，但对Ⅰ、Ⅱ期前列腺癌及纤维腺癌样型前列腺增生，两者仅凭CT影像较难鉴别。结论：CT在前列腺增生与前列腺癌的鉴别诊断中占有重要地位。
OBJECTIVE: To compare the CT findings of benign prostatic hyperplasia with prostate cancer and to improve the diagnostic accuracy of the two methods. Materials and Methods: A retrospective analysis was performed on 23 cases of benign prostatic hyperplasia (BPH) and 22 cases of prostate cancer confirmed by prostate biopsy or surgical pathology from 1986 to 1997. Results: After statistical processing, both shapes. Density, bladder wall thickened P value <0.01, calcification P value> 0.05. In addition, prostate cancer may still appear adjacent to the violation of the organ and the transfer of signs, but for Ⅰ, Ⅱ prostate cancer and fibroadenoid type of benign prostatic hyperplasia, CT images alone difficult to identify. Conclusion: CT plays an important role in the differential diagnosis of benign prostatic hyperplasia and prostate cancer.
