A longitudinal study of changes in Diffusion Tensor Value and their association with cognitive sequelae among patients with mild head injury.

Abstract Diffusion tensor imaging (DTI) is an advanced and sensitive technique that detects sub-threshold pathology in normal imaging brain injury patients. Currently, there are no longitudinal DTI studies to look for time-based changes. The present study has investigated longitudinal imaging and its association with cognitive deficits. Twenty-one patients were available for MRI and neuropsychological test (NPT) assessment for all the 3 time points. Initially (
