摘要 目的:探讨多模态磁共振成像(MRI)对前列腺癌的诊断价值。方法回顾性分析我院2011年4月~2014年3月31例经病理证实的前列腺癌患者的术前多模态 MRI影像资料,包括常规磁共振成像(常规 MRI),动态对比增强磁共振成像(DCE-MRI),扩散加权磁共振成像(DWI),磁共振氢质子波谱分析(1 H-MRS),以探讨多模态MRI在前列腺癌诊断中的价值。结果前列腺癌常规 MRI T2 WI癌灶呈低信号结节,多位于外周带,动态增强检查癌灶时间信号强度曲线(TIC)呈速升速降型(III型),DWI检查癌灶弥散明显受限,MRS表现为(Cre +Cho)值明显增高,Cit值明显降低。结论多模态MRI对前列腺癌具有重要诊断价值。
