体素内不相干运动成像在脑肿瘤中的研究进展

Intravoxel incoherent motion imaging:research advances in brain tumors

体素内不相干运动(intravoxel incoherent motion,IVIM)成像近年来已成为脑肿瘤常规影像的重要补充,因其可同时获得脑肿瘤扩散和灌注信息,有利于更全面了解肿瘤生理病理变化及肿瘤微环境的信息。目前,IVIM已在脑肿瘤的术前诊断、分级诊断及脑胶质瘤基因型预测和预后评估中取得了一定的成果。该文将综述IVIM基本原理及其在脑肿瘤中的临床应用现状。

Intravoxel incoherent motion(IVIM)imaging has become an important supplement to conventional brain tumor imaging in recent years.It can obtain the information of brain tumor diffusion and perfusion at the same time,which is conducive to a more comprehensive understanding of tumor physiological and pathological changes and tumor microenvironment.Recently,IVIM has achieved certain results in preoperative diagnosis,grading diagnosis,genotype monitoring and prognosis evaluation of glioma.This article will review the basic principle of IVIM and its clinical application in brain tumors.
