目的 研究多模态MRI检查在前列 腺Ca诊断中的应用价值。方法 选取我院 泌尿外科2014年4月-2016年4月收集的50 例前列腺癌患者(均由穿刺活检病理或者 外科手术证实)的多模态MRI影像资料(常 规MRI、DCE-MRI、DWI和MRS)进行回顾性 分析，探讨分析多模态MRI在前列腺癌中 的应用价值。结果 前列腺癌在常规MRI中 呈现为T2W1低信号，病灶常位于外周区； DCE-MRI呈现为快进快出样延缓弧线(III 型)；DWI呈现为弥散受阻，ADC值降低； MRS呈现为Cho值显著上升，Cit值显著降 低，Cre + Cho和Cit比值上升。结论 联 合应用DCE-MRI、DWI和MRS行多模态MRI进 行早期诊断前列腺癌准确度较高，使用多 模态MRI对前列腺癌患者进行诊断值得在 临床应用和推广。

Objective To study the application value of multi modality MRI in the diagnosis of prostate Ca. Methods Selected and analyzed retrospective the MRI imaging data (MRI, DCE-MRI, DWI and conventional MRS) of 50 cases of prostate cancer patients with multimodality from the Department of Urology in our hospital, to investigate and analyze the application mode of MRI in prostate cancer. Results Prostate cancer in conventional MRI showed low signal on T2W1, the lesions often located in the peripheral zone; DCE-MRI has fast sample delay statements impassability] [arc (III); DWI showed diffuse blocked, ADC decreased. MRS showed the Cho value increased, Cit value decreased significantly, Cre + and Cho the ratio of Cit increased. Conclusion The combined application of DCE-MRI, DWI and MRS in the early diagnosis of prostate cancer is of high accuracy, the use of multi modality MRI in the diagnosis of prostate cancer is worthy of clinical application and promotion.
