| 摘 要： | 体素内不相干运动(intravoxel incoherent motion,IVIM)成像是指体素内信号衰减的同时包括真性水分子弥散和毛细血管网中随机血流微循环灌注,它可以更加全面地分析组织扩散成像数据,揭示疾病的病理生理学改变。近年来,IVIM逐渐被应用于临床研究中,在各个器官及系统的疾病诊断中发挥重要作用。

| Abstract: | The concept of intravoxel incoherent motion (IVIM) imaging has demonstrated that the diffusion-weighted signal can be influenced not only by molecular diffusion but also by microcirculation. It allows a more comprehensive analysis of datas of diffusion-weighted imaging (DWI). In recent years, IVIM has been used in clinical research. It will play an important role in the diagnosis of diseases in various organs and systems. |
