摘要
磁共振脑血流灌注 加权成像是功能磁共振成像的一个重要组成部分。本文重点介绍了磁共振脑血流灌注加权成像的基本原理,在急性脑缺血疾病诊断中的应用,以及磁共振脑血流灌注加权成像的应用前景和展望。
MR perfu-sion-weighted
imaging is an important part of the func-tional MR imaging. Some advantages in the field were described in detail includ-ing the basie principle of MR perfusion -weighted imaging, application of imaging
diagnosis in acute brain ischemia and its future and prospect.
