Fig 2. T2 relaxation times of gray matter regions (cerebral cortex, thalamus, hippocampus, and cerebellar cortex and white matter regions (corona radiata, centrum semiovale, internal capsule, and cerebellar white matter [bottom]) were determined in unaffected and AMD cats. Significant increases in T2 were found in the white matter of AMD cats compared with unaffected cats (*P < .05). No significant differences in T2 were found between affected and normal cats when gray matter regions were compared.
