本研究涉及灌注定量健康志愿者使用两种类型的动态磁共振成像（MRI）的方法。应用外源性造影剂团注追踪和无创动脉自旋标记MRI技术对11例受试者进行了绝对脑血流量（CBF）测量。两种方法产生的CBF图像具有良好的组织对比度，CBF值与文献数据吻合良好。本文还讨论了脑血容量（CBV）与CBF的相关性。(C)2000 Elsevier Science Inc. All rights reserved.
This study deals with perfusion quantification in healthy volunteers using two types of dynamic magnetic resonance imaging (MRI) methods. Absolute cerebral blood flow (CBF) measurements were performed in 11 subjects by applying both bolus tracking of exogenous contrast agent and non-invasive arterial spin labeling MRI techniques. Both methods produced CBF images with good tissue contrast and CBF values are in good agreement with literature data. The correlation between cerebral blood volume (CBV) and CBF is also discussed.
