Application of CT and Magnetic Resonance Imaging in Diagnosis of Craniocerebral Trauma
Objective:To investigate the clinical value of CT and magnetic resonance imaging in the diagnosis of craniocerebral trauma.Methods:50 cases of craniocerebral trauma were selected from January 2021 to November 2022,and CT examination and magnetic resonance imaging were performed.The positive rate of diffuse axonal injury was compared and analyzed by the two examination methods,and the detection of lesions were compared by the two examination methods.Results:In MRI examination,the positive rate of diffuse axonal injury was 82.00%,29 cases were positive for diffuse brain swelling,14 cases were positive for subarachnoid hemorrhage,23 cases were positive for ventricular hemorrhage,11 cases were positive for epidural hematoma,10 cases were positive for hemorrhagic lesion and 32 cases were positive for non-hemorrhagic lesion.In CT examination,the positive rate of diffuse axonal injury was 54.00%,11 cases were positive for diffuse brain swelling,26 cases were positive for subarachnoid hemorrhage,42 cases were positive for ventricle hemorrhage,20 cases were positive for epidural hematoma,25 cases were positive for hemorrhagic lesion and 16 cases were positive for non-hemorrhagic lesion.The positive detection rates of diffuse brain swelling,subarachnoid hemorrhage,ventricle hemorrhage,non-hemorrhagic lesions and non-hemorrhagic lesions by MRI were higher than those by CT,and the difference was statistically significant(P<0.05).Magnetic resonance imaging showed 25 cases of extra-axial injury,13 cases of deep brain contusion and 45 cases of intracerebral injury,including 31 cases of frontal lobe injury and 14 cases of temporal lobe injury.CT examination showed 21 cases of extra-axial injury,4 cases of deep brain contusion and 38 cases of intracerebral injury,among which 25 cases of frontal lobe injury and 13 cases of temporal lobe injury.The number of cases of extra-axial injury and deep brain contusion detected by MRI was higher than that by CT,and the difference was statistically significant(P<0.05).Conclusion:Both CT and magnetic resonance imaging can play a diagnostic role in the diagnosis of craniocerebral trauma.However,compared with CT,magnetic resonance imaging has a higher detection rate of lesions,which is suitable for application in severe patients and improves the diagnostic accuracy.Clinical examination can be combined with the actual situation of patients to select the appropriate examination methods.
