ABSTRACT：ObjectiveTo analyze the MRI artifact of the inner ear structure in patients with peripheral vertigo acquired by using 3D fast imaging employing steady state acquisition （3D FIESTA-C） and 3D fast spin echo （3D-Cube T2）.MethodsData of 63 patients with peripheral vertigo treated in the Department of Otolaryngology， The First Affiliated Hospital of Xi'an Jiaotong University，from October 2O23 to June 2024 were filtered for analysis.Thepatientsconsistedof16malesand47females，aged18to6Oyearsold.Twoseniorradiologists independently evaluated the quality of the acquired images through the two MRI sequences.Kappa test was used to evaluate theconsistencyof thetworadiologists’subjective judgments，and Wilcoxon signed-rank test was used to compare the imagequality between each sequence.The accuracyof 3DFIESTA-C，3D-Cube T2 and combination of the two sequences was calculated in the presentation of inner ear structure.ResultsThe overallimage quality of 3D-CubeT2wasbetterthan that of 3DFIESTA-C（ Z=-11.670 ， P<0.001 ），and theaccuracyof 3DFIESTA-C combined with 3D-Cube T2 was superior to that of each sequence in demonstrating the semicircular canals.The demonstration accuracy of horizontal semicircular canal among three scan protocols was statistically different （ P< 0.001）.Conclusion3DFIESTA-C has the advantage in detecting horizontal semicircular canal，and 3D-Cube T2 always provides high quality images of upper semicircular canal. Compared with each scanning sequence，3D FIESTA-C combined with 3D-Cube T2 can effectively avoid misdiagnosis or missed diagnosis of semicircular canal structuresin the patientswith peripheral vertigo.
