脑灌注主要是描述脑血管网中的血流情况。从MR灌注的基本原理及概念、对比剂的应用、成像方法、图像资料的后处理等几个方面阐明MR灌注成像外源示踪剂的基本技术并简述了其他技术方法。通过对MR灌注不同脑肿瘤血供特点的研究,胶质瘤术前分级的研究,对脑肿瘤治疗和治疗后效果的评估以及肿瘤复发与放疗后坏死的鉴别等方面的介绍,阐明其在脑肿瘤研究方面的应用以及这种新技术的最新发展趋势。
Cerebral perfusion mainly describes the blood flow in the cerebral blood vessel network. The basic techniques of MR perfusion imaging tracer and the other techniques are described from the basic principles and concepts of MR perfusion, application of contrast media, imaging methods, post-processing of image data. Through the study on the characteristics of blood supply of different brain tumors by MR perfusion, the preoperative grading of glioma, the evaluation of the effect of brain tumor after treatment and treatment, and the identification of tumor necrosis after tumor recurrence and radiotherapy, The application of tumor research and the latest development trend of this new technology.
