Résumé
Objective: To investigate the value of MR three-dimension brain volume imaging (3D-BRAVO) enhanced scanning in diagnosis of internal auditory canal lesion. Methods: Eighty-one patients with internal auditory canal disease (totally 116 lesions) underwent 3D-BRAVO enhanced and conventional enhanced MR scanning. The sensitivity of methods was compared. Results: Conventional MR enhanced scanning found 86 lesions, the diagnostic sensitivity was 71.55% (83/116), and the misdiagnose rate was 28.45% (33/116). All 116 lesions were detected with 3D-BRAVO enhanced scanning, and the diagnostic sensitivity was 100% (116/116). The diagnostic sensitivity of 3D-BRAVO scanning was higher than that of conventional enhanced scanning (Z=-3.74, P<0.001). Conclusion: 3D-BRAVO enhanced scanning can sensitively detect lesions in the internal auditory canal area and provide imaging evidences for clinical diagnosis and treatment of these lesions.
