Visualization of inner ear disorders with MRI in vivo: from animal models to human application.

Conclusion: The inner ear membranous permeability and leakiness and endolymphatic hydrops can be visualized using gadolinium-enhanced MRI in both rodents and man. Intratympanic administration of contrast agent gives greater perilymphatic loading of gadolinium.

Objectives: Visualization of different types of inner ear dysfunction in MRI with intravenous or intratympanic administration of contrast agent.
