Assessment And Significance Of Susceptibility-weighted Imaging To Patients With Mild Traumatic Brain Injury

Objective: To explore the assessed value of3.0Magnetic resonance susceptibilityweighted imaging (SWI) of patients with mild brain trauma; detection sensitivitydifferences between SWI Clinical comparison with conventional MRI and SWIMTBI hemorrhagic foci.Methods: Wuhan Zhongnan Hospital from November2011to November2012during neurosurgery inpatient and outpatient emergency department traumatic braininjury patients screened54cases of mild brain trauma patients meet the clinicaldiagnostic criteria. All subjects were injured within a week to accept the skull CT,MRI, and SWI check whether the lesion by two high qualification, MD, Departmentof Radiology, consensus count of each sequence showed lesions, lesions havequestions not statistics. Combination of CT and phase diagram exclude small bloodvessels, the brain foreign body, air and skull base artifacts, low signal SWI Figureintracranial hemorrhage. Exploration to the number of lesions on conventional MRIsequences and SWI were recorded location (in accordance with the cerebral cortex,white matter, leather medullary junction, corpus callosum, basal ganglia, brain stem,cerebellum seven brain partition), distribution characteristics, gross morphology andboundary.Results:33patients presented as coma onset, while21cases had none consciousdisturbance, of which20and10cases post-traumatically developed to post traumaticbrain syndrome (PTBS), respectively. Based on SWI, patients with consciousdisturbance showed higher incidence of hemorrhagic focus (87.9%:57.1%, p=0.010),whereas patients with hemorrhagic focus demonstrated higher probabilities to havePTBS (63.4%:30.8%, p=0.039).19(35.2%) and28(51.9%) cases each were detectedto have hemorrhagic foci by TSE and FLAIR, with28and41foci were foundrespectively. By contrast,41(75.9%) cases showed hemorrhagic foci on SWI, withtotal foci as134. SWI showed higher sensitivity than FLAIR and TSE(75.9%:51.9%:35.2%), with p less than0.001by chi-square test. Foci detected bySWI were also more than those detected by FLAIR and TSE (mean,2.48:0.76:0.52),with p both less than0.001by paring sample Wilcoxon rank test.Conclusion: SWI shows higher sensitivity than gMRI in detecting hemorrhagic focusof MTBI patients. SWI shows higher sensitivity than gMRI in detecting hemorrhagicfocus of MTBI patients. Parenchymal hemorrhage may impact long-term outcome ofMTBI patients, while SWI can offer some valuable and objective information, in this aspect. MTBI brain tissue of patients MHF, and prompted its exist with PIBS ofclosely related.
