Table 3.
Ratio between average uptakes in the target region and cerebellar cortex using data in the time interval 40–60 min (late uptake ratio). The groups are defined in the text. Only patients with arterial sampling are included. Means and SDs of the samples are presented. The standardized difference is described in the text
