Análise da radiodensidade das substâncias cinzenta e branca na tomografia de crânio de doentes com lesão axonal difusa

Abstract

Objectives: Diffuse axonal injury (DAI) produces a devastating effect on the individual and there is considerable difficulty to diagnose it with the use of computed tomography (CT), only tool available at the Emergency Hospital of Sergipe (HUSE). This study aims to seek an objective alternative diagnostic DAI using the CT. Methods: We retrospectively evaluated CT scans of 20 patients who were divided into two groups: patients with DAI and control patients treated at HUSE from May 2015 to July 2015. Results: Three variables were evaluated: the radiodensity the grey matter, averaging 45.27 UH DAI group and 45.74 UH in control; the white matter averaging 31.75 UH in the group with DAI and 32.92 UH in control; and the average GM/WM reasons mean the DAI group 1.43 and 1.39 in the control. Conclusion: Although in this study no significant difference in the variables studied, we observed a greater variation of radiodensity values in white matter between the groups.
