The Application Value Of Susceptibility-w Eighted Imaging In Severe Traumatic Brain Injury

Objectives:To investigate the application value of susceptibility-weighted imaging in severe traumatic brain injury. Compare the differentiation of lesion of severe traumatic brain injury patients in magnetic Susceptibility-Weighted Imaging and MR conventional sequences(TIWI, T2 WI and FLAIR) and CT scan. Methods:We selected 40 cases with severe traumatic brain injury.28 male cases, 12 female cases, aged range from 3 to 74. 8 hours to 3 days after injury, MR generic sequence scan line SWI sequence selection, at the same time the shortest time interval CT scans.40 cases of severe craniocerebral injury(severe traumatic brain injury, s TBI) traffic accident injury in 25 cases, patients with high falling injury in 5 cases, hit 4 cases, accidental fall injury in 5 cases, 1 case of unknown cause injury. Glasgow(GCS) score(Glasgow Coma Scale, 3-8 points. Case inclusion criteria: Glasgow(GCS) score≤eight points and six hours of patients with acute craniocerebral injury. Anyone with cerebral infarction, cerebral hemorrhage, brain tumor, vascular malformations, cerebral white matter degeneration diseases were excluded. Patients admitted to hospital after conventional outfit CT examination, after being condition allows, check before are explained to family members of the inspection process in place to ensure that its inspection, restlessness patients cannot fit check prior to the inspection sedated. Using MR750 3.0 MRI scan system, SWI, MR generic sequence checks, during the same period costumes CT examination. SWI image after late reconstruction with CT, MR generic sequence, together with the analysis, record the sequence of the amount of hemorrhage stove and their positions. Hemorrhage stove and vascular section in the count, blood vessels around the lacuna, calcifications, calcium iron deposit showed low signal phase identification, etc. The latter is beyond the scope of the count. Results:CT, MR conventional sequence, SWI for severe craniocerebral injury lesions number respectively is 276,551,2338. the result display rate were 100%,199.64%,810.87%.SWI for the number of severe craniocerebral injury patients with intracranial lesions was much higher than that of CT and MR conventional sequence, and the radiographic imaging more clear, injury focal distribution range and more clear, more observation. Conclusion:Trauma group of patients with moderately severe craniocerebral injury patients found in the SWI focal injury significantly more than MR sequence and conventional CT found in kitchen, it has been verified by the experiment, SWI for deep brain tissue injury more sensitive detection of the oven. Especially for deep brain tiny lesion morphology and the distribution of the show more clear, clear. Found after comprehensive comparison of three kinds of tests: SWI focal intracranial injury in patients with severe craniocerebral injury were detected with MR conventional sequence, the superiority of CT to match. Therefore SWI for the diagnosis and differential diagnosis of patients with severe craniocerebral injury patients of scientific evaluation and prognosis in patients with prognostic offers a clear and accurate imaging basis, it has important application value in the field of brain injury. Magnetic sensitive weighted imaging has important value in the diagnosis of severe traumatic brain injury.
