Summary
Brain lesions caused by infections, tumours and some other diseases, often cannot be distinguished from each other clinically or by neuro-radiology examinations. A brain biopsy is usually needed to make a definite diagnosis and may cause sequelae or not be possible if the lesion is in certain areas of the brain. Magnetic resonance imaging (MRI) has increased our ability to detect brain lesions but cannot unequivocally diagnose the disease process.

A brain biopsy is usually needed to make a definite diagnosis and may cause sequelae or not be possible if the lesion is in certain areas of the brain. Magnetic resonance imaging (MRI) has increased our ability to detect brain lesions but cannot unequivocally diagnose the disease process. Magnetic resonance spectroscopic (MRS) methods report on the chemical composition of lesions and can provide a simultaneous picture of the location of the lesion and the pathology of the disease process. Brain biopsies may therefore be avoided in a significant number of cases where drainage or decompression of lesions are not needed as part of therapy. Identification of specific fingerprints for the different diseases will provide a rapid, robust, automated diagnosis, which will expedite management decisions and improve patient outcomes. It should also be possible to monitor the efficacy of drug treatments using MRS methods. Each of these outcomes would constitute a major medical advance.Read moreRead less
Single Shot X-ray Tomography For Real-Time Functional X-ray Imaging

Funding Amount
$322,641.00
Summary
Computed Tomography (CT) scanners produce three-dimensional images of vital organs that cannot be obtained by conventional two-dimensional (single projection) x-ray radiographs. However, the radiation exposure is hundreds of times higher than conventional radiography. We will develop the world’s first CT scanner that uses no more radiation than a single conventional x-ray image that will provide four-dimensional reconstructions of a patient’s moving internal organs.
Infrared Spectroscopic Imaging In The Diagnosis Of Cervical Cancer

Summary
In Victoria alone around 500000 Pap smears a year are examined for evidence of cancer of the cervix or conditions that may lead to cancer. This is a time consuming, labour intensive and costly process with a relatively high failure rate. A number of alternative techniques have been explored in the last decade with a view to providing a diagnostic technique that is free of human error, more reliable than the Pap method and easily used.

This is a time consuming, labour intensive and costly process with a relatively high failure rate. A number of alternative techniques have been explored in the last decade with a view to providing a diagnostic technique that is free of human error, more reliable than the Pap method and easily used. An alternative technique based on using infrared light to probe smears shows promise in providing such an easily automated reliable method. We, and others have spent a number of years exploring this technique and have solved a number of the problems associated with it. Based on our work in the field and the work of others we now wish to develop a methodology using an infrared micro-imaging spectrometer combined with multivariate statistics that can be used to diagnose cervical cancer and the conditions that lead to cervical cancer.Read moreRead less
Longitudinal Studies Of Knee Osteoathritic Changes Using Magnetic Resonance Imaging (MRI)

Funding Amount
$420,872.00
Summary
The associations between MRI-assessed knee structural changes and radiographic changes over 5 years in older people will be determined. The effects of physical activity in adults and childhood, and the roles of inflammation will be described. The study represents a cost-effective comprehensive approach to osteoarthritis, a major public health problem, and is a natural progression of previous work that supports the objectives of the Bone and Joint Decade and addresses a national health priority.
Centre Of Research Excellence In Precision Public Health Approaches To Breast Cancer Screening, Early Detection And Mortality Reduction

Funding Amount
$2,500,000.00
Summary
The ultimate aim of the CRE is to make it possible to further reduce mortality from breast cancer, and in a more effective way, by identifying women at vastly different levels of risk at younger ages, determining which screening modalities are likely to be more effective, and helping radiologists to better detect cancers. Given that digital mammography is the contemporary standard, and the incidence of breast cancer is increasing across the world, this CRE has global relevance.
Cancer And Low-dose Radiation - Possible Effects Of CT Scans In Childhood
Funder

Funding Amount
$476,650.00
Summary
Despite 100 years of research there is uncertainty about effects of low dose radiation from background and medical X-rays. We will measure the incidence of cancer in Australians exposed to CT scans (medical X-rays) as children between 1985 and 2005. Our results, from follow-up to 2009, will show whether there is a small but signicantly increased risk of cancer and guide further improvement in radiation safety standards if these prove to be necessary.
A New Non-invasive Diagnostic Technique Based On Detection Of Exhaled Respiratory Pathogens.

Summary
We developed a special collection mask and showed that the breath of people with colds or flu contains a tiny amount of virus. Currently, diagnostic samples are collected by putting a tube into the airways - this is very uncomfortable. Our masks may provide a new and more comfortable way to diagnose lung infections. We want to build better masks and ways to detect viruses and bacteria to test out this method. This may create a new test that will improve diagnosis and treatment.

Summary
Autologous chondrocyte implantation (ACI) is the ‘gold standard’ for treating knee cartilage defects. Traditionally, ACI was performed through open surgery. However, ACI can now be performed through ‘keyhole’ surgery, decreasing the co-morbidity of open surgery. Furthermore, optimal patient outcome is limited by a lack of knowledge in effective post-operative rehabilitation.

Detection of infrared-biomarkers for the diagnosis and treatment of canine neoplasia. This research hopes to discover infrared-biomarkers for canine cancers using synchrotron infrared and laser light. Many dog cancers are similar to human cancers so cancerous tissues and cells from dogs make excellent models for human cancer research. This project will provide new insights and technological approaches to cancer diagnosis and treatment.

Summary
Fundamental electromagnetic modelling of light-biological tissue interactions: a platform for future medical microscopy. Methods for modelling the fundamental electromagnetic interaction of light with biological tissue will be developed. This will allow a range of biomedical optical images to be properly interpreted ultimately leading to the holy grail of quick and minimally invasive methods for detecting cancer.
