将新鲜血液成像(FBI)获得的上肢非对比增强磁共振静脉成像(MRV)与飞行时间(TOF)-MRV进行比较。三条静脉(贵要静脉、臂静脉和头静脉)、小分支和脂肪抑制的可视化用四分制(0-3)进行评估。FBI-MRV对贵要静脉和小静脉分支的显示明显优于TOF-MRV，对臂静脉和头静脉的显示效果与TOF-MRV相当，在脂肪抑制方面无差异。FBI-MRV可用于静脉标测和血栓检测。(C)2012 Elsevier Inc.保留所有权利。
Non-contrast-enhanced magnetic resonance venography (MRV) of the upper limb acquired by fresh blood imaging (FBI) was compared with time-of-flight (TOF)-MRV. Visualization of three veins (basilic, brachial, and cephalic veins), small branches, and fat suppression was evaluated with a four-point scale (0-3). FBI-MRV was significantly superior for the basilic veins and small venous branches and equivalent for the brachial and cephalic veins to TOF-MRV, with no difference in fat suppression. FBI-MRV would be useful in venous mapping and detection of thrombus. (c) 2012 Elsevier Inc. All rights reserved.
