CT and MR perfusion imaging of the liver:techniques and clinical applications

近年来随着CT、MR功能成像研究的发展,国内外有不少学者尝试使用CT、MR肝脏灌注成像评价肝脏功能及肝脏病变的血液动力学特征。综述了近来国内外CT、MR灌注成像在肝脏评价中的应用现状,重点是图像分析方法及临床应用。

In recent years the functional imaging techniques of CT and MR including perfusion imaging have developed fast. Some studies are attempting to evaluate the hepatic function and the hemodynamic characteristics of the hepatic lesions by using CT or MR perfusion imaging. The purpose of this article is to review the recent studies of the applications of CT and MR perfusion imaging to the evaluation of the liver. The main topics are imaging analysis and clinical applications.
