MR扩散峰度成像在腹部的研究现状

摘要

Diffusion kurtosis imaging ( DKI ) is a kind of novel MRI technology enabling characterization of non-Gaussian water diffusion behavior. Although DKI has been largely applied in neurological diseases with good effect over the past decade, a small number of studies have recently explored DKI in other than brain, for example, prostate, kidney, liver and so on. The most investigated organ in abdomen is the prostate, and DKI has improved tumor detection and grading. This article aimed to review the application and advances of DKI in abdomen.%磁共振扩散峰度成像（DKI）是一种反映体内水分子非高斯分布扩散运动状态的MR成像新技术。近年来DKI已广泛应用于神经系统，并取得良好的效果。目前也逐步被应用于前列腺、肾脏、肝脏等体部脏器成像，其中在前列腺的应用最为广泛，通过应用DKI可提高对前列腺肿瘤诊断与分级的能力。就DKI技术在腹部的应用研究现状予以综述。
