Abstract:
Objective:To investigate the diagnostic value and imaging features of high resolution magnetic resonance imaging(HR-MRI)in patients with lesions in carotid artery and intracranial artery.Methods:Sixty-nine patients with suspected lesions in carotid artery and intracranial artery who admitted to Handan Central Hospital from June 2021 to December 2023 were selected,and they underwent routine MRI and HR-MRI examinations.Digital subtraction angiography(DSA)examination was used as the"gold standard"to analyze the detection rates of different MRI examinations for lesions in carotid artery and intracranial artery.The diagnostic efficacy of them was calculated,and the HR-MRI imaging features of positive cases and negative patients were compared under the"gold standard".Results:For 69 patients with suspected lesions in carotid artery and intracranial artery,41 cases(59.42%)were confirmed by"gold standard"examination,and 31 positive cases were confirmed by routine MRI examination,and 35 positive cases were confirmed by HR-MRI examination,and 39 positive cases were confirmed by combined examination of routine MRI and HR-MRI.The results indicated that the accuracy,sensitivity,specificity,positive and negative predictive values of the combined examination of routine MRI and HR-MRI were respectively 88.41%,87.80%,89.29%,92.31%and 83.33%,all of which were higher than those of single image examination,and the differences were statistically significant(x2=5.459,7.329,6.216,6.395,6.141,P<0.05).The irregular shape,blurred boundary,high signal,plaque formation,intra-plaque bleeding,displacement of common carotid artery or vein,and calcification of lesion in HR-MRI imaging features of positive patients were significantly higher than those of negative patients,and the differences were statistically significant(x2=8.918,4.418,7.001,4.746,8.743,5.951,4.947,P<0.05),respectively.Conclusion:The detection rates both of routine MRI and HR-MRI are higher in patients with lesions in carotid artery and intracranial artery.However,the combined examination of them can improve the diagnostic sensitivity and specificity,and the morphology,boundary,signal and calcification foci of confirmed patients are more obvious in HR-MRI examination,which can provide reference for subsequent diagnosis and treatment.
