在6名年轻的健康志愿者中，将一种使用磁共振（MR）团注追踪测定脑血流量（CBF）的新方法与[O-15]H2O正电子发射断层扫描（PET）进行了比较。该方法产生的参数CBF图像与组织对比度与参数PET CBF图像吻合良好。引入一个共同的转换因子，MR CBF值可以转换为绝对流量，允许比较正常受试者之间的CBF值。
In six young, healthy volunteers, a novel method to determine cerebral blood flow (CBF) using magnetic resonance (MR) bolus tracking was compared with [O-15]H2O positron emission tomography (PET). The method yielded parametric CBF images with tissue contrast in good agreement with parametric PET CBF images. Introducing a common conversion factor, MR CBF values could be converted into absolute flow rates, allowing comparison of CBF values among normal subjects.
