In six young, healthy volunteers, a novel method to determine cerebral blood flow (CBF) using magnetic resonance (MR) bolus tracking was compared with [(15)O]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.
在6名年轻健康志愿者中，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[（15）O]H2O正电子发射断层扫描（PET）进行了比较。该方法生成的参数化CBF图像与参数化PET CBF图像在组织对比度方面具有良好的一致性。引入一个通用转换因子后，MR CBF值可以转换为绝对流速，从而能够比较正常受试者之间的CBF值。
