Left/right ratio of total counts for the entire cerebellar hemisphere and for each slice in craniocaudal direction.NP=not performed. To avoid partial volume effects, the upper and lower slices were not considered (cranial slice1, caudal slice 5). The normal range (mean ± 2.5 SD) of left/right ratio has been reported as 0.82-1.18 (Perani et al 14).
