Blood Flow Measurements

In six young, healthy volunteers, a novel method to determine cerebral blood flow (CBF) using magnetic resonance (MR) bolus tracking was compared with [15O]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.

Blood Flow Measurements

Two consecutive measurements of resting CBF were carried out in normal volunteers (n = 25) using H215O positron emission tomography. Absolute whole-brain blood flow (WBBF; ml 100 g−1 min−1, mean ± SD) for the first (40.3 ± 6.4) and second (39.3 ± 6.5) measurements was not significantly different (mean % difference 2.3 ± 8.7). Analysis of regions of interest showed no significant differences in absolute regional CBF (rCBF) and normalized (rCBF/WBBF) rCBF. Left-right differences were also not significant. These data demonstrate the reproducibility of resting CBF measurements in normal humans.
