HMPAO tracer uptake of the cerebellar hemisphere in patients with dysarthria due to extracerebellar lacunar stroke.
| Patient | Cerebellar hemisphere | Slice 1 | Slice 2 | Slice 3 | Slice 4 | Slice 5 |
|---|---|---|---|---|---|---|
| 1 | 0.98 | 1.02 | 1.00 | 0.95 | 0.99 | 0.96 |
| 2 | 0.97 | 0.99 | 0.99 | 0.97 | 0.95 | 0.97 |

| 4 | N.P. | NP | NP | NP | NP | NP |
| 5 | 0.94 | 0.90 | 0.91 | 0.97 | 1.04 | 0.87 |

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).
