【摘要】目的：分析常规MRI平扫、DWI联合动态增强扫描(DCE-MRI）在前列腺癌(Prostatic Cancer PC）诊断中的价值。方法方便选取2015年1月一2016

年6月该院接收的60例疑似前列腺癌(PC）患者为研究对象，行常规MRI平扫、DWI联合动态增强扫描(DCE-MRI）。并对比病理诊断结果，评价诊断准确率。结果经病理证实42例前列腺癌，其中11例B期，占26.2%；19例C期，占

45.2%；7例D1期，占16.7%；5例D2期，占11.9%。所有确诊患者合并前列腺增生。其余为良性前列腺增生(BPH），合并前列腺炎10例；确诊38例，准确率为90.5%。结论MRI平扫、DWI联合动态增强扫描可明显提升前列腺癌确诊率，减少误诊风险，为临床治疗提供有效保障，建议临床采纳并推广。%Objective To analyze the MRI plain scan, dynamic enhanced scanning combined with DWI in the diagnosis of prostate cancer (PC) value. Methods In 60 cases from January 2015 to June 2016 of suspected patients with PC as the ob-ject of study, diagnosis of epidemic conventional MRI plain scan, dynamic enhanced scanning and DWI. And compared with the results of pathological diagnosis, evaluation of the diagnostic accuracy rate. Results Pathologically confirmed 42 cases of PC, That is, 11 cases of B period, accounting for 26.2%;19 cases of C period, accounting for 45.2%; 7 cases

of D1 peri-od, accounting for 16.7%; 5 cases of D2 period, accounting for 11.9%. of all diagnosed patients with benign prostatic hy-

perplasia.Remaining for benign prostatic hyperplasia (BPH), 10 cases with

prostatitis; diagnosis of 38 cases, the accuracy rate was 90.5%. Conclusion MRI plain scan, State enhanced scan combined with DWI can significantly improve the diag-nostic rate of PC, reduce the risk of misdiagnosis, and provide effective protection for clinical treatment, it is recommended to adopt and promote clinical.

从目前情形来看前列腺癌的发病率有地域性，其中美国居首，中国等亚洲国家次之。但国内情况也不容乐观，比如在前列腺癌诊断上确诊率较低，误诊现象层出不穷［1］。该文现以常规MRI平扫、DWI联合动态增强扫描（DCE-MRI）在前列腺癌（PC）诊断中的价值为研究目的，以2015年1月—2016年6月该院接收的

60例疑似前列腺癌患者为研究对象，现报道如下。

1.1 一般资料

方便选取该院接收的60例疑似前列腺癌患者为研究对象，年龄在54～91岁之间，平均年龄为（70.2± 10.2）岁，所有结果经穿刺活检或手术病理证实；MR检查

前所有患者均未接受内分泌、放射治疗等相关治疗，该次研究患者均签署知情同意书，并获得医院伦理委员会批准。

1.2 方法

行常规MRI平扫、DWI联合动态增强扫描：①常规MRI平扫：选择磁共振机
