Diffusion-weighted imaging (DWI) plays an emerging role for the assessment of focal and diffuse liver diseases. This growing interest is due to that fact that DWI is a noncontrast technique with inherent high contrast resolution, with promising results for detection and characterization of focal liver lesions. Recent advances in diffusion image quality have also added interest to this technique in the abdomen. The purpose of this review is to describe the current clinical roles of DWI for the detection and characterization of focal liver lesions, and to review pitfalls, limitations, and future directions of DWI for assessment of focal liver disease.
扩散加权成像（DWI）在局灶性和弥漫性肝脏疾病的评估中发挥着新兴作用。这种日益增长的兴趣源于 DWI 是一种具有固有高对比度分辨率的无对比技术，在检测和描述局灶性肝病变方面具有有前景的结果。扩散图像质量的最新进展也增加了该技术在腹部的应用。本综述的目的是描述 DWI 在检测和描述局灶性肝病变中的当前临床作用，并回顾 DWI 在评估局灶性肝病中的陷阱、局限性和未来方向。
