Exploration of the Application of MRI Magnetic Sensitive SWI Technology in the Diagnosis of Craniocerebral Tuberculosis

Objective:To investigate the diagnostic effect and value of MRI susceptibility weighted imaging(SWI)technology in patients with craniocerebral tuberculosis.Methods:From January 2018 to January 2021,60 patients with suspected craniocerebral tuberculosis were selected as subjects.After admission,all patients were given MRI magnetically sensitive SWI technology and ordinary enhanced scanning,and were cultured with tuberculosis,smear and pathology.Check the"gold standard"for comparison,and analyze the detection rate,diagnostic efficiency and imaging characteristics of cranio-cerebral tuberculosis under MRI magnetic sensitivity SWI technology.Results:60 cases of suspected craniocerebral tuberculosis patients were diagnosed with 45 cases;MRI enhanced scanning was diag-nosed in 38 cases,with a diagnostic sensitivity of 66.67%(30/45)and a specificity of 46.67%(7/15);MRI magnetically sensitive SWI technology confirmed the diagnosis For 42 cases,the diagnostic sensi-tivity was 84.44%(38/45)and the specificity was 73.33%(11/15);44 cases were diagnosed by MRI magnetic sensitivity SWI technique combined with MRI general enhancement,and the diagnostic sensi-tivity was 93.33%(42/45),The specificity was 86.67%(13/15);among the 45 patients who were finally diagnosed,42 of them were irregular patch-like and linear thickening of the brain cistern or(and)the meninges on the brain surface under the MRI magnetic sensitive SWI technique.And there was obvious enhancement after enhancement;7 cases were accompanied by hydrops,5 cases had multiple lacunar infarctions,no obvious enhancement was seen after enhancement,and the MRI magnetically sensitive SWI showed iso-signals.Conclusion:MRI magnetically sensitive SWI technology has a high detection rate in patients with craniocerebral tuberculosis,combined with MRI general enhanced scanning,has high diagnostic sensitivity and specificity,and has typical imaging characteristics,which can provide a reference for clinical diagnosis and treatment.
