Description

This funding opportunity aims to support high risk clinical trials for the development of in vivo high-resolution structural and functional imaging technologies for the living human inner ear. Proposed projects should focus on improving the resolution of current imaging techniques or developing new imaging techniques that can visualize inner ear structures in vivo with significantly greater detail and accuracy than currently possible. Structural and functional aspects, including visualizing dynamic elements, are important to developing new and improved techniques. Projects may also focus on developing new imaging probes or contrast agents that can enhance visualization of the inner ear structures. Research supported in response to this RFA is expected to significantly advance the ability to visualize auditory and vestibular components, such as hair cells, otoliths, membranes, ions, and vasculature, in detail in awake patients in a clinical setting using non-invasive techniques. To achieve this goal, a multidisciplinary team approach that takes advantage of the expertise of each team member is highly encouraged. Studies in humans must be proposed to develop,advance, or test the needed technology. Any intermediate studies must articulate a clear path of the proposed methodology to application in awake humans or define the limitations and the usefulness in anesthetized humans.
