MR弥散加权成像在胰腺病变的应用进展

Progress of diffusion weighted imaging in pancreatic lesions

近年来弥散加权成像及其衍生序列包括体素内不相干运动、小视野弥散加权成像、弥散张量成像已经越来越广泛的应用于胰腺病变的诊断及鉴别诊断,具有重要的临床价值;而弥散峰度成像及拉伸指数模型同样具有一定应用价值,本文就磁共振弥散加权成像及其衍生序列在胰腺病变的应用作一总结。

In recent years, diffusion-weighted imaging and its derivative sequences including intravoxel incoherent motion, reduced field-of-view diffusion weighted imaging, anddiffusion tensor imaging have been widely applied to the diagnosis and differential diagnosis of pancreatic lesions, which has important clinical value. The diffuse kurtosis imaging and stretched exponential model also have certain application value. In this paper, the application of MR diffusion weighted imaging（DWI） and its derived sequences in pancreatic lesions is summarized.
