Clinical value of magnetic resonance imaging in the diagnosis of inner ear lesion

Abstract

Objective To discuss the clinical value of magnetic resonance imaging in the diagnosis of inner ear lesion. Methods 94 patients who took magnetic resonance imaging water imaging were selected as study subjects from February 2014 to October 2016 in Heilongjiang Province Hospital.All the patients had surgical data, CT, MRI water imaging data.Based on the standard data of surgery gold, analyzed the sensitivity, specificity, accuracy, positive predictive value and negative predictive value of CT and MRI in the diagnosis of inner ear lesions, compared the statistical differences between the two methods of examination. Results The sensitivity, specificity, positive predictive value and negative predictive value of MRI water imaging in diagnosis of inner ear were higher than CT, but the differences were no statistically significant (all P>0.05). In the case of abnormal vestibular aqueduct(χ2=7.265, P=0.015), cochlear deformity(χ2=5.042, P=0.028), diagnostic accuracy of cochlear fibrosis(χ2=5.492, P=0.027), the differences were statistically significant(all P<0.05). Conclusion MRI water imaging can effectively provide the information of ear canal, endometrial and other internal organs, can provide a favorable clinical diagnosis, it is worth to promote the application in the clinical work. Key words: MRI inner ear water imaging; Vestibular aqueduct; Cochlear deformity; Sensitivity; Accuracy
