摘要 扩散加权成像（ Diffusion weighted imaging ， DWI）是磁共振功能成像之一，是在分子布朗运动基础上分析病变内部结构及组织成分，通过间接获取的微观病理组织学信息，无创地反映活体组织功能状态的检查技术。 DWI在中枢神经系统缺血性疾病的超早期诊断价值已得到公认［1，2］，但是早期的DWI成像时间长，对呼吸运动、肠蠕动等高度敏感，故在上腹部的临床应用受限。近年来，随着MR设备和技术的进步，尤其是回波平面技术（ EPI ）的不断成熟，DWI的应用逐步延伸到颅脑以外的人体器官， DWI在腹部的运用越来越受到重视，其在腹部脏器应用的研究报道也日益增多［3，4］。目前己采用了多种技术克服上述不足，包括屏气技术、自由呼吸、呼吸及心电门控、快速梯度回波、平面回波成像和并行采集技术等，使DWI在腹部的检查中趋于成熟。本文就近年来DWI用于胰腺疾病诊断方面的应用做一简单综述。
