Abstract:
Objective To investigate the relationship between MRI classification and both time of awakening and prognosis in patients with long-term consciousness disorders after traumatic brain injury. Methods Sixty-six patients, admitted to our hospital from 2003 to 2008 and suffered from severe traumatic brain injury with consciousness disorders for more than 2 weeks, were collected. The cranial MRI data of all patients were recorded and classified; the awakening time of all conscious patients after injury was recorded; the prognoses were judged by Glasgow outcome scale 6 month after the injury.The relationship between MRI classification and both time of awakening and prognosis were analyzed.Results The prognoses (the scores of Glasgow outcome scale) were closely associated with the cranial MRI classification; the higher the MRI classification, the poorer the prognosis; the accuracy rate of MRI in assessing the prognosis was 83.33%. The average awakening times were (8.00±4.10) weeks in patients with graded Ⅰ and Ⅱa of MRI classification, and (22.67±23.66) weeks in patients with graded Ⅱb and Ⅲ of MRI classification. Conclusions The MRI classification is correlative to the prognosis and the awakening time of the patients with long-term consciousness disorders after severe traumatic brain injury.Using MRI classification can objectively and accurately evaluate patients' prognosis.
