Shown are the median ± mean absolute deviation from median (with the coefficient of variation (CV) between parentheses) of cerebral blood flow (CBF) and arterial transit time (ATT). ACA, MCA and PCA refer to the flow territories perfused by the anterior, middle and posterior cerebral arteries respectively, corresponding to Fig 2. Difference (4th column) shows whether the median or CV differed (Y) or not (N) (p<0.01) between CBFcrushed and CBFnon-crushed.
