ABSTRACT
Objective To investigate the clinical application of SWI in detecting calcifications of vertebral artery wall.Methods 1 95 patients who accepted craniocerebral CT scans,and MRI scans (includingT1 WI,T2 WI,T2 GFLAIR,SWI)in recent three years in the Affiliated Hospital of Binzhou Medical University were reviewed.Taking CT as a standard,the calcification of intracranial vertebral artery wall was analyzed using conventional MRI and SWI sequences,and their sensitivities and specificities were calculated.Correlations among various imaging modalities were assessed by measuring the maximum diameter of calcifications.Results The sensitivity of SWI was 93%, and the specificity of SWI was 9 9%.The sensitivity of conventional MRI was 3 1%,and the specificity of conventional MRI was 9 1%. The correlation between SWI and CT was R2=0.77 (0.60-0.89),while the correlation between conventional MRI and CT was R2=0.22 (0.02-0.80).Conclusion SWI has high sensitivity and specificity in detecting calcification of intracranial vertebral artery wall,and has a good correlation with CT in measuring calcification,which can be a inspection method to detect calcification of intracranial vertebral artery wall.
