| 摘 要： | 磁共振扩散峰度成像（DKI）是扩散加权成像（DWI）、扩散张量成像（DTI）的延伸与补充，可进一步揭示生物体内水分子运动的非高斯扩散模型，更适合反映人体内微环境，较DWI、DTI技术可提供更准确、真实、丰富的组织微观结构信息。DKI技术问世以来，逐渐应用于各系统疾病的研究，尤其是在神经系统疾病中取得了显著成果，展现出良好的临床价值。DKI可反映微观信息，具有巨大的应用前景，在肝脏疾病方面的研究也越来越多，笔者就DKI在肝脏疾病中的应用予以综述。

| Abstract: | Diffusion kurtosis imaging (DKI) is the extension and supplement of diffusion weighted imaging (DWI) and diffusion tensor imaging (DTI). DKI further reveals the Non-Gaussian diffusion model of water molecule movement in organisms. DKI is more suitable for reflecting the micro-environment of human body and provides more accurate, real, and rich organizational microstructure information compared with DWI and DTI technologies. DKI has been gradually applied to the study of diseases in various systems, particularly the nervous system. This technology has achieved remarkable results and shows good clinical value. DKI can reflect microscopic information and has great application prospects. Currently, this technology is contributing to the increase in the number of research works on the liver. This article reviews the application of DKI to the study of liver diseases. |
