本文旨在研究磁共振血流成像(MRA)在颅脑疾病的应用价值及最佳方法选择。60例脑血管疾病MRA检查中,48例用两种以上MRA方法检查,24例做了DSA对照。研究结果显示:无出血时,脑动脉狭窄、动脉瘤应首选MOTSA;AVM首选多流速编码的2D-PC,并联用3D-TOF或3D-PC;有明显出血时,各种病变均应首选3D-PC。
This article aims to investigate the value of magnetic resonance imaging (MRA) in brain disease and the best method of choice. Of the 60 MRA examinations of cerebrovascular diseases, 48 were examined by two or more MRA methods and 24 were DSA controls. The results show that: no bleeding, cerebral artery stenosis, aneurysm should be preferred MOTSA; AVM preferred multi-flow-coded 2D-PC, parallel with 3D-TOF or 3D-PC; obvious bleeding, various lesions should be preferred 3D -PC.
