Summary
We don't understand what happens during a non-epileptic seizure. Patients can't tell us and we can't use normal brain scanning during a seizure as the patient moves too much. Our idea is to take patients with non-epileptic seizures on the epilepsy wards who are being monitored and inject them with a radioactive tracer as soon as the seizure starts, then we can scan them afterwards to see what parts of their brain were active during the seizure, so we will understand what was happening.
Importance Of The Transmural Distribution Of Viable Myocardium To Outcome Of Patients After Revascularization

Summary
After a heart attack, up to 50% of tissue showing reduced function can recover if blood supply is returned to normal with bypass surgery or balloon angioplasty. Because these procedures may be risky in cardiac patients, the investigators have used various imaging approaches including radionuclide and ultrasound techniques to predict regions where function will recover after intervention. The results of these tests may be discordant because they assess separate attributes of cardiac muscle, and s ....After a heart attack, up to 50% of tissue showing reduced function can recover if blood supply is returned to normal with bypass surgery or balloon angioplasty. Because these procedures may be risky in cardiac patients, the investigators have used various imaging approaches including radionuclide and ultrasound techniques to predict regions where function will recover after intervention. The results of these tests may be discordant because they assess separate attributes of cardiac muscle, and selection of patients for intervention on the basis of recovery of regional function ignores some other aspects that may be important. These include avoidance of heart enlargement, improvement of exercise capacity, and avoidance of heart rhythm disturbances and even other heart attacks. In this study, the investigators seek to define the importance of the proportion and site of live (viable) myocardium to the parameters listed above. A new magnetic resonance technique will be used to identify whether radionuclide and ultrasound techniques assess different parts of the heart wall. The relative importance of these sites will be identified by comparing the outcome of patients who have live tissue in the inner half, compared with the outer half of the heart wall. This study will involve 180 patients who will undergo testing with magnetic resonance and radionuclide imaging. A subgroup will undergo dobutamine echocardiography. Their responses over follow-up will be assessed by accurate evaluation of heart size, exercise response, heart rhythm abnormalities and clinical events.Read moreRead less
Development Of A New Surgical-guidance Tool For Intra-operative Tumour Margin Assessment In Breast Cancer

Summary
One third of breast cancer patients undergoing breast conserving surgery have insufficient tissue removed, resulting in an increased risk of recurrence. We have developed a high resolution optical imaging probe with the potential to detect small areas of cancer. It could be used to help guide the surgeon to remove all cancerous tissue from the patient. This grant will allow us to develop the probe to a stage that it can be used during surgery, and perform the world’s first clinical scans.
Development Of Microscope-in-a-needle Devices For Improved Clinical Diagnostics

Summary
We have developed a new high-resolution optical imaging technology. The unique aspect of our research has been to redesign the imaging probe, miniaturising it to a few hundred microns in diameter, and encase it in a hypodermic needle – a ‘microscope-in-a-needle’. We are developing specific imaging probes to aid in the assessment of lung disease; the diagnosis of liver disease; and integrated into a brain biopsy needle to enable safer brain biopsies.
Advances in positron emission tomography now allow specific pathological features of many brain diseases such as Alzheimer's disease to be measured with a brain scan during life. This Fellowship will assist Professor Rowe and his team in their world leading work on new PET scanning techniques to improve diagnosis and assist the development of treatment for Alzheimer's and other degenerative diseases of the brain.
Improving Human FMRI Through Modeling And Imaging Microvascular Dynamics

Funding Amount
$486,144.00
Summary
In this project we aim to establish a reliable vascular baseline to improve mapping of both small-scale functional architecture and large-scale brain networks in functional human brain mapping using MRI. By mapping the grey matter vasculature with high detail in both humans and animals, and by computing and matching of these atlases across species we will be able to validate this approach in vivo to confirm the better spatial specificity of the newly developed approach.
Non-invasive Near-infrared Optical Imaging Of Neurodegeneration

Summary
Dementia currently affects over 240,000 Australians with an increasing health cost. A common cause of dementia occurs when proteins in the brain form deposits and brain cells degenerate and die. This project will develop a novel medical imaging method that will facilitate the detection of dying brain cells. This will enable a better understanding of the causes of cell death and the opportunity to identify the best time for meaningful therapeutic intervention.
