National Institute on Deafness and Other Communication Disorders (NIDCD)
Purpose: To improve existing, and discover new, imaging techniques in terms of resolution and functional capabilities to provide accurate and timely diagnoses for humans in the clinic.
Background: The National Institute on Deafness and Other Communication Disorders (NIDCD) is issuing this Notice of Special Interest (NOSI) to highlight priorities as outlined in the 2023-2027 Strategic Plan (https://www.nidcd.nih.gov/about/strategic-plans) and a previous workshop on Visualizing the Human Inner Ear, held Nov. 2019. NIDCD encourages the development of imaging techniques for application in humans, and in animals if readily applicable to humans, to significantly increase the resolution for visualizing living tissue in greater detail within the clinical setting. Increases in functional imaging capabilities in vivo for humans are also desired. NIDCD supports basic, translational, and clinical research on hearing, balance, taste, smell, voice, speech, and language. While advanced imaging technologies are widely used to diagnose disease or injury and inform treatment and its effectiveness, within our mission areas, some imaging techniques are lacking or do not have the necessary capability to visualize with cellular or structural resolution. This type of resolution and/or functional imaging would provide for a detailed diagnosis of the underlying cause of dysfunction of the human auditory, vestibular, olfactory, and gustatory systems. In addition, improved imaging technologies are also needed to examine the functional aspects of disorders of voice and speech. New, improved imaging capabilities are likely to increase the accuracy of diagnoses and aid treatment. NIDCD encourages multidisciplinary teams, e.g., neuroscientists paired with clinicians and engineers, to spearhead innovative projects. Diverse teams may also pair with industry to advance imaging techniques to an entirely new level of resolution and functionality that does not currently exist to view structures that are encased in thick bone, evade definitive visualization with current techniques, provide information about functional processing at cellular or sub-cellular resolution, or require dynamic visualization. Applications will need to integrate appropriate domains of expertise, including but not limited to biological, chemical, and physical sciences, engineering, neuroscience, imaging, and clinical knowledge. These projects may include invasive techniques pursuant to the ultimate goal of non-invasive imaging techniques to be used in the clinic at a resolution capable of visualizing, for example, hair cells, movement of hair cells, membranes, supporting cell layers, otoliths, movement of otoliths with head positioning, canal integrity, perilymph fluid distribution, vasculature changes, neurotransmitter use, ion channel differences, vocal fold movements, and the olfactory epithelium.
Objectives: This NOSI aims to encourage grant applications that propose innovative approaches to developing high-resolution imaging technologies for structures such as the inner ear, olfactory epithelium, taste buds, and vocal production structures during disordered speech. Proposed projects should focus on improving the resolution of current imaging techniques or developing new imaging techniques that can visualize cellular, sub-cellular, and molecular structures and functions. New imaging developments should consider reducing the burden of imaging procedures on cost, invasiveness, and procedure time. The new and improved techniques must have the potential to be translated to use with humans in the clinic, preferably in an awake state.
By mission area, the lists below include representative, but not exhaustive, examples of topics that could be considered responsive to this NOSI.
Hearing and Balance: The inner ear contains critical sensory organs that play essential roles in hearing and balance. The complex anatomy, including encasement in thick bone, and small size of the structures within these sensory organs have posed significant challenges for imaging technologies. While various imaging modalities exist, none currently provide sufficient resolution to fully visualize the inner ear. Therefore, the development of high-resolution imaging technologies is essential for improving the diagnosis and treatment of inner ear disorders pursuant to both hearing and vestibular disorders.
Chemical Senses: There are limited technologies currently available to visualize chemosensory structures in a clinical setting for diagnosis, treatment, and monitoring of olfactory and taste disorders. Such disorders can arise due to many factors including aging, injury, viral infection, inflammation, or environmental insult. One challenge with commonly used endoscopy is that the olfactory epithelium is generally indistinguishable from the respiratory mucosa. Advances in noninvasive imaging tools and technologies, such as fluorescent imaging, specialized endoscopes, and dyes, and technologies are needed to visualize chemosensory targets, and to monitor specific chemosensory cell types and/or their activity in real-time.
Voice and Speech: Movements of structures within the oral cavity including the tongue and vocal tract, and folds within the larynx are critical components in creating voice and speech output. Technologies exist for viewing these structures during disordered communication but improvements in dynamic imaging and resolution of each structure would greatly assist in evaluation, diagnosis, treatment, and rehabilitation. Challenges persist in providing low-cost, non-invasive, imaging options for awake, behaving patients in a clinical setting that also include the capability of dynamic imaging.
