The Diagnostic Value of 1.5T Versus 3.0T Magnetic Resonance Imaging Intratympanic Gadolinium Inner Ear Enhancement in Patients with Meniere’s Disease

BACKGROUND: A comparative study of 1.5T and 3.0T magnetic resonance imaging inner ear gadolinium enhancement was carried out to further explore the practicality and universality of 1.5T magnetic resonance imaging in the diagnosis of inner ear labyrinthine hydrops positive imaging. METHODS: This dual case–control study was conducted on 25 patients with Meniere’s disease (experimental group), diagnosed by People’s Hospital of Ordos Dongsheng District between April 2017 and April 2019 and 51 patients with Meniere’s disease (control group), diagnosed by People’s Hospital Affiliated to Fujian University of Traditional Chinese Medicine between March 2010 and February 2011 and published on Chinese Medical Journal in 2011. Both groups were injected with gadolinium diluent into bilateral tympanic chambers through the tympanic membrane, and 3 dimensional-Fluid Attenuated Inversion Recovery (FLAIR) magnetic resonance imaging scanning of the inner ear was performed 24 hours later. The results of the 2 groups were observed, calculated, and statistically processed. RESULTS: The positive rate of membranous labyrinthine hydrops was 96% (24/25) in the experimental group and 96.1% (49/51) in the control group. The results are very close. CONCLUSION: In clinical diagnoses of Meniere’s disease, 1.5T magnetic resonance imaging and 3.0T magnetic resonance imaging have the same value and significance.
