| 摘 要： | 磁共振扩散峰度成像(diffusion kurtosis imaging,DKI)是扩散张量成像(diffusion tensorimaging,DTI)技术的延伸,该技术的主要优势是可以量化组织内水分子非高斯扩散的特性,对人体组织微观结构的复杂状态比其他技术更敏感,进而能够提供更多的结构变化信息并反映疾病的病理生理改变,有利于在疾病早期进行定性诊断并尽早指导临床决策。目前,DKI技术在临床多种疾病和科研中都有较多的应用,作者对DKI在脑肿瘤中的国内外研究进展进行综述。

| Abstract: | Diffusion kurtosis imaging(DKI) is an extension of diffusion tensor imaging(DTI) technology, which can quantify the non-gaussian diffusion characteristics of water molecules in tissues. It is more sensitive to the complex microstructure of human tissues than other technologies, and it can provide more information about structural changes and reflect the pathophysiological changes of diseases, which is conducive to early detection of diseases and early guidance of clinical decision-making. At present, DKI technology has been widely applied in clinical diseases and scientific research. This paper mainly reviews the research progress of DKI in brain tumors at home and abroad. |
