Official Title: Diffusion Tensor Imaging to Judge the Prognosis of Patients With Diffuse Axonal
Brief Summary: The investigators will examine 15 patients who was firstly diagnosed as diffuse axonal injury and 15 patients negative for magnetic resonance examination with no trauma with DTI(diffusion tensor imaging). The investigators then determine the FA（fractional anisotropy）value and the ADC(apparent diffusion coefficient) value of relational interesting area（corpus callosum、brainstem、basal ganglia）to analyse the correlation between the FA（fractional anisotropy）value and ADC(apparent diffusion coefficient) value and GCS(Glasgow Coma Scale) and coma time,so that the investigators can quantify the damage degree of patients' white matter fiber.By using fiber tractography the investigators can have the extent of recovery of the patient of DAI（diffuse axonal injury） in real-time detection and give guidance for the clinical decision and the judgement of prognosis).
