Three-dimensional image analysis of trauma-induced degenerative changes: an aid to neuropsychological assessment.
A single case study is presented that depicts three-dimensional (3D) reconstruction of the day of injury computerized tomogram (CT) findings with the degenerative changes identified by magnetic resonance imaging (MR) 18 months postinjury. The method allows the clinician to examine 3D changes in the ventricular system as an aid in identifying regions of structural damage in one view rather than the need to view multiple images with the traditional two-dimensional (2D) presentation of CT or MR images. In this case study the neuropsychological deficits implicated generalized cerebrocortical dysfunction and the 3D image analysis correspondingly indicated generalized parenchymal tissue loss. This type of methodology is discussed in terms of furthering the neuropsychological-neuroimaging interface.
