摘　　要：目的分析膀胱受累的前列腺癌的MRI表现,评价MRI对前列腺癌的定性诊断价值,避免伴膀胱受累的前列腺癌误诊为膀胱肿瘤。资料与方法回顾性分析15例行MRI检查前曾误诊为膀胱癌的前列腺癌患者的临床及MRI资料。结果 15例误诊病变MRI均明确诊断为前列腺癌,其中C期10例,D期5例。结论 MRI是诊断前列腺癌良好的影像学方法,特别是当病变累及膀胱时,可很好地避免误诊为膀胱肿瘤,再结合其他检查方法,可提高前列腺癌的诊断准确率。Objective To analyze magnetic resonance imaging（MRI） features of prostate cancer with bladder invasion,and to avoid misdiagnosis as bladder cancer.Materials and Methods Clinical and MRI imagings of 15 patients with prostate cancer with bladder invasion,which were misdiagnosed as bladder cancer before MRI Examination were retrospectively reviewed.Results MRI accurately diagnosed 15 cases of prostate cancer included 10 cases of stage C and 5 of stage D.Conclusion MRI is a good technique in diagnosing prostate cancer with bladder invasion and will greatly improve the diagnostic accuracy.
