Corpus callosum injury in patients with diffuse axonal injury: a diffusion tensor imaging study.
Little is known about diffusion tensor image (DTI) findings of corpus callosum (CC) injury in patients with diffuse axonal injury (DAI). In the present study, we investigated the presence and extent of CC injury in patients with DAI. Twenty patients with DAI and 20 age-and sex-matched normal healthy controls subjects were recruited. ⋯ FA values of the six sagittal segments in the CC (-) and (+) groups were significantly lower than those of controls, and ADC values were slightly higher, or showed no change. CC lesions may be present in DAI patients, irrespective of detection on conventional brain MRI. The authors suggest the probability that in cases of corpus callosum injury, DTI can offer a powerful means of detecting DAI.
