Serum levels of protein S100B predict intracranial lesions in mild head injury.

Objectives: This study was aimed to assess whether serum S100B levels at emergency department admission can be used to omit unnecessary computed tomography (CT) in patients with minor head injury (MHI).

Design And Methods: Sixty consecutive patients with recent MHI were included in this study. Serum S100B measurement and CT scanning were performed in all patients within 3h from head injury.
