| 摘 要： | 目的:评价MR扩散加权成像对前列腺癌的诊断价值。方法:搜集有手术或穿刺病理结果的前列腺疾病患者15例,其中前列腺癌10例,前列腺炎5例。所有病例均行MR常规T1WI、T2WI及DWI扫描。回顾性分析各组病例的MR常规表现及DWI表现。结果:在MR扩散加权图像上,8例前列腺癌表现为外周带内局限性显著高信号,其余病变在扩散加权成像上为低信号或等信号。结论:MR扩散加权成像对前列腺癌有重要的鉴别诊断价值。

| Abstract: | Objective:To evaluate the diagnostic value of DWI in prostate carcinoma.Methods:Ten cases of prostate carcinoma,and five cases of prostatitis proved by operation or systemic biopsies were collected.All cases underwent routine MR T_1WI,T_2WI and DWI.Results:All prostate cancers showed high signal intensity in the peripheral zone on DWI,the rest showed low or equal signal intensity.Conclusion:DWI plays an important role in the differential diagnosis of prostate carcinoma.[ |
