Application Value Of Delayed CE-T2-FLAIR In Traumatic Brain Injury

Objective : 1.5T magnetic resonance was used to perform conventional magnetic resonance plain scan,CE-T1 WI and delayed CE-T2-FLAIR examination on patients with traumatic brain injury.Statistical analysis of three groups of images showed brain traumatic lesions.Comparison and analysis of two enhanced examinations of meningeal enhancement situation and correlation with clinical symptoms,to explore the application value of delayed CE-T2-FLAIR in traumatic brain injury.Methods:From January 2018 to March 2020,30 patients with brain trauma who met the inclusion criteria in the Department of Neurosurgery,Fifth Affiliated(Zhuhai)Hospital of Zunyi Medical University were selected as the research objects.30 patients underwent conventional magnetic resonance plain scan,T1 WI enhancement,and delayed CE-T2-FLAIR in order.Collect clinical data such as patient's gender,age,GCS score,injury history,presence or absence of headache and transient loss of consciousness,and divide each patient's magnetic resonance image into MRI plain scan,CE-T1 WI,delayed CE-T2-FLAIR.Observe and count the three groups of images for brain parenchymal injury and intracranial hematoma,statistically analyze CE-T1 WI,delayed CE-T2-FLAIR meningeal enhancement score and meningeal enhancement degree.The chi-square test was used to analyze whether the three groups of images showed statistical differences in brain parenchymal injury,intracranial hematoma,and positive images.Paired sample t test analysis was used to compare the two enhancement tests for meningeal enhancement score and meningeal enhancement degree.Differences were compared using Spearman rank correlation analysis to compare the correlation between the meningeal enhancement score,the degree of meningeal enhancement,clinical manifestations,brain parenchymal injury,and intracranial hematoma with delayed CE-T2-FLAIR and CE-T1 WI.Results:(1)The number of delayed CE-T2-FLAIR positive images is higher than that of MRI plain scan and CE-T1WI(P<0.05),and the number of delayed CE-T2-FLAIR meningeal enhancement is higher than CE-T1WI(P<0.05).(2)Delayed CE-T2-FLAIR meningeal enhancement score and meningeal enhancement degree are higher than CE-T1WI(P<0.05).(3)Delayed CE-T2-FLAIR meningeal enhancement score was positively correlated with headache,brain parenchymal injury,and subdural hemorrhage(P<0.05).(4)Delayed CE-T2-FLAIR meningeal enhancement degree was positively correlated with transient loss of consciousness and subdural hemorrhage(P<0.05).(5)CE-T1 WI meningeal enhancement score was positively correlated with headache,brain parenchymal injury,and subdural hemorrhage(P<0.05).(6)CE-T1 WI meningeal enhancement degree has no correlation with clinical manifestations,brain parenchymal injury,and intracranial hematoma(P>0.05).Conclusion:(1)Delayed CE-T2-FLAIR can find more signs of positive imaging when the MRI scan of TBI patients is negative and CE-T1 WI images are negative.(2)Delayed CE-T2-FLAIR shows better range and degree of meningeal enhancement in TBI patients than CE-T1 WI.(3)Delayed CE-T2-FLAIR and CE-T1 WI meningeal enhancement scores and the degree of delayed CE-T2-FLAIR meningeal enhancement are related to headache,transient loss of consciousness,brain parenchymal injury,and subdural hemorrhage in TBI patients.
