Summary
Deafness, both congenital and acquired, is likely to be one of the major causes of disability in the Australian workforce, in young Australians, and in some categories of pre-term infants in the next decade or two. While not life-threatening, hearing impairment deprives individuals of one of their most basic social needs: the ability to communicate with others. Although little can be done to recover lost hearing, it is important to detect hearing loss as early as possible in order to reduce furt ....Deafness, both congenital and acquired, is likely to be one of the major causes of disability in the Australian workforce, in young Australians, and in some categories of pre-term infants in the next decade or two. While not life-threatening, hearing impairment deprives individuals of one of their most basic social needs: the ability to communicate with others. Although little can be done to recover lost hearing, it is important to detect hearing loss as early as possible in order to reduce further loss (by behaviour modification in the case of noise-exposed adults) and to provide hearing assistance in very young children so that they may be exposed to some degree of auditory experience at as early an age as possible. To this end, the phenomenon of otoacoustic emissions, or noises from the ear, now recognised for twenty years, is likely to become even more significant in the early years of the next millennium. Otoacoustic emissions were first demonstrated as very soft echoes re-emerging from the ear after a delay of ten milliseconds or so following a click stimulus. These echoes are sounds produced by the ear as it goes about its normal function and are lost if the hearing sensitivity of the individual is below normal. Several other forms of otoacoustic emissions have been discovered and rapidly applied to the testing of hearing so that today the technique of assessing hearing status in neonates and others unable to co-operate, as well as in diagnostic applications, is widespread. The application of the technique, however, has preceded a real understanding of what otoacoustic emissions are and how they are generated, and their widespread use at the moment is somewhat akin to a car repair industry which does not understand how an engine works. This proposal intends to investigate the basic mechanisms behind otoacoustic emissions in order to improve their efficiency and accuracy of clinical interpretation.Read moreRead less
Improving The Assessment Of Brain Tumour Treatment Outcome Using 18F-FDOPA PET-MRI Fusion

Summary
The mortality rate within the first year of diagnosis for high-grade brain tumours is approximately 80%. A major factor contributing to poor outcome measures is the limitation of current neuroimaging techniques. In a novel approach we propose to combine the information available from MRI and PET images to better define the extent of the tumour and provide markers of early treatment response. This improved diagnostic information should improve survival rates.
Molecular Imaging To Advance Treatment Of Dementia

Funding Amount
$412,419.00
Summary
Molecular imaging using a scan technique called positron emission tomography, enables detection and measurement of specific pathological features of disease such as the amyloid plaques of Alzheimer’s disease. This project will develop this technology for other aspects of brain disorders including dementias, Parkinson’s disease, traumatic brain injury and schizophrenia and use it to assist development of therapies and improve clinical diagnosis nation wide.

The Use Of Positron Emission Tomography (PET), Novel Immune And Microbiological Biomarkers To Improve The Diagnosis And Prognostication Of Giant Cell Arteritis

Summary
Giant cell arteritis (GCA) is an inflammatory condition of blood vessels. Diagnosing the condition and predicting which patients will develop complications is challenging. Undiagnosed, a significant proportion of patients experience sudden onset, permanent blindness. Our study aims to improve the diagnosis and risk assessment of patients with suspected GCA by following a group of 65 patients for two years with serial scans, blood tests and clinical reviews.
