Application Value Of 3.0T Magnetic Resonance Susceptibility Weighted Imaging In Contusion And Laceration Of Brain

Objective Discuss the performance of hemorrhagic lesions of Contusion and Laceration of Brain on SWI sequence of 3.0T magnetic resonance and evaluate the application value of SWI in Contusion and Laceration of Brain.Methods Retrospective analysis patients in March 2014 to February 2015 to our hospital with clear and definite injury and are proposed to be diagnosed Contusion and Laceration of Brain, all patients are performed sequential scans such as conventional CT, T1WI, T2WI, DWI, SWI and the like. Analyze the image feature of Contusion and Laceration of Brain on SWI sequence; compare detected cases and number of lesions of intracerebral hemorrhage in SWI and conventional MRI sequence. Compare different Glasgow Coma Scale (GCS), which is classified as mild, moderate and severe contusion and laceration of brain. Use statistical software SPSS 19.0 to process data information. Compare the diagnostic value of SWI, such as conventional MR sequence in Contusion and Laceration of Brain.Results 58 cases of positive patients are collected. For patients with Contusion and Laceration of Brain, most intracerebral hemorrhage lesions presented low signal in SWI sequence lesions. A total of 1163 lesions was presented in SWI, much more than conventional sequence, and the difference is statistically significant (P<0.05). The number of SWI lesions is obviously related with GCS score (r=-0.486, P<0.01), the number of SWI lesions in cortical and subcortical structure is not related with GCS score (r=0.099, P=0.459),and the number of SWI lesions in midline brain structure is obviously related with GCS score (r=-0.681, P<0.01)Conclusion SWI showed a clear and accurate Contusion and Laceration of Brain, more and smaller lesions may be detected in SWI than conventional sequence, providing a more reliable iconography basis for clinical applications. SWI has potential clinical value.
