摘要
目的综述肝脏弥散加权磁共振成像的检查技术及其研究进展。方法采用文献回顾的方法,对近年来国内、外有关肝脏弥散加权磁共振的成像原理和研究现状加以分析与综述,同时展望了一些需要进一步研究的问题。结果磁共振弥散加权成像通过测量肝脏内的水分子弥散运动,从而了解肝脏局灶性和弥漫性病变与肝脏正常结构和功能的差异。随着各种快速成像技术的出现以及对弥散动力学研究的深入,肝脏弥散成像技术已经逐步走向成熟,可用于肝脏病变的诊断和鉴别诊断,为临床诊断、治疗提供更多有用的信息。结论弥散加权成像作为一种无创性的检查方法,可为临床及影像医生提供多种反映肝脏功能的指标参数,具有相当大的发展前景。
Objective To review the examination techniques and the current research progress of the magnetic resonance diffusion weighted-imaging (DWI) used in liver. Methods The recent and relevant literatures about the principles and the current study situation of liver DWI were scrutinized and analyzed retrospectively. In addition, the existing problems of liver DWI were discussed. Results DWI could demonstrate the normal and abnormal structure and function through measuring the diffusion motions of water molecule in the liver. With the improving technology and better understanding of diffusion dynamics, DWI has been used for the diagnosis and differential diagnosis for hepatic diseases. Conclusion DWI as a non-invasive examine method, may provide valuable functional information for clinical diagnosis and treatment.
