摘要
磁共振弥散加权成像是目前磁共振用以观察活体组织水分子扩散运动理想且唯一的成像方法,可以对组织中水分子的扩散程度进行定性和定量测量。随着磁共振技术的不断发展,尤其是快速成像序列的开发,弥散加权成像在肝脏、胰腺、肾脏等实体器官的应用已非常普遍,在空心脏器胃中的应用也逐步展开,本文主要阐述弥散加权成像在胃癌诊断治疗中的研究现状。
With the capability of measuring the water molecular diffusion qualitatively and quantita- tively, diffusion weighted imaging （DWI） is currently the optimal and the only magnetic resonance method to observe water molecular diffusion motion in living tissues. Along with the advances in magnetic resonance tech- nology, particularly the development of fast imaging sequences, DWI has been widely used in the imaging of liver, pancreas, kidneys and other solid organs. In recent years, DWI has been applied in the stomach. This article summarizes recent research on the application of DWI for the diagnosis and treatment of gastric cancer.
