Abstract
Diffusion tensor imaging (DTI) tractography was used to evaluate five children with hearing loss or impaired language development. Our first case involved a 5-year-old boy with unilateral hearing loss apparently due to callosal disconnect. The second case involved a 10-year-old girl with developmental Gerstmann syndrome. The third, fourth, and final cases involved 3 children who experienced difficulty acquiring the ability to read Japanese kana characters. Each image depicted on DTI tractography was compatible with the results of neuropsychological testing. Thus, DTI tractography is suitable for clinical use in pediatric audiology and logopedics. Because results from DTI tractography are unchanged even if the subject is sedated, DTI tractography offers advantages over functional magnetic resonance imaging for young children.
