腹部IVIM-DWI应用研究及进展
Research application and advances of IVIM-DWI in abdomen
摘要
Abstract
Concept of intravoxel incoherent motion (IVIM) has demonstrated that the diffusion-weighted signal can be influenced not only by molecular diffusion but also by microcirculation. Therefore, apparent diffusion coefficient (ADC) values may limit the reliability in characterizing lesions. Microcirculation or perfusion effect can be distinguished from true tissue diffusion by using sufficient b value sampling and a biexponential curve fit analysis with the IVIM model.It allows a more comprehensive analysis of DWI data, and has been widely used in evaluation of liver, pancreas, kidney, prostate and other organs. This article aims to review research application and advances of IVIM-DWI in abdomen.关键词
