摘要
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 T2W 1, the lesions often located in the peripheral zone; DCE-MRI has fast sample delay statelnents impassabilityl [arc （Ⅲ）： DWI showed diffnse 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.
