My aim is to use advanced Neuroimaging to further our understanding of the pathophysiology of brain disorders, in particular Epilepsy, but also Sleep disorders, Schizophrenia, the Dementias. In the case of my main research interest (Epilepsy) it is to red
Evaluation Of Renal Masses Using Magnetic Resonance

Summary
This project will investigate use of an imaging instrument to identify renal cancers that are potentially harmless from aggressive renal cancers. Currently, such differentiation requires biopsies, and the outcome is often unnecessary surgical removal of whole or part of the diseased kidney. Long term, this project will provide knowledge to determine aggressiveness of a renal cancer non-invasively, without having to perform an operation. The approach was previously successful for breast cancer.

Brain surgery for the treatment of epilepsy is associated with a risk of cognitive impairment. Avoidance of disabling post-operative impairments depends in large measure on our ability to predict and measure individual patterns of language lateralization prior to neurosurgical intervention. Typical patterns of lateralisation cannot be assumed in patients with epileptogenic lesions. There appears to be a consensus that atypical representation is more frequent in patients with epilepsy than it is ....Brain surgery for the treatment of epilepsy is associated with a risk of cognitive impairment. Avoidance of disabling post-operative impairments depends in large measure on our ability to predict and measure individual patterns of language lateralization prior to neurosurgical intervention. Typical patterns of lateralisation cannot be assumed in patients with epileptogenic lesions. There appears to be a consensus that atypical representation is more frequent in patients with epilepsy than it is in the normal population, and values above 20% are not unrepresentative Partial epilepsy arises from a region in the brain and spreads to involve other areas. This is contrasted with generalised epilepsy, which appears to arise all over the brain simultaneously. Partial epilepsy is often associated with lesions such as tumors or hippocampal sclerosis, and often seizures are intractable. Patients with partial epilepsy have a number of sources of brain damage in the language areas. Primary brain changes may be pre-existing, which means they pre-date the onset of habitual seizures. They may consist of a focal developmental abnormality (a malformation of cortical development) or may represent a general genetic predisposition to seizures. Therefore, partial epilepsy is not only associated with severe abnormalities in epileptogenic region but also with additional widespread abnormalities in both hemispheres. There is also evidence for a correlation of abnormalities with seizure frequency with some suggestion that the duration of epilepsy may also increase the degree of abnormality in the hemisphere. The neuronal conditions in language cortex that give rise to altered lateralisation in function are currently not known. The primary aim of this study is to understand reorganisation of the language system in epilepsy by using the current most sensitive non-invasive methods of assessing brain damage and brain function, using magnetic resonance imaging.Read moreRead less
Improving Human FMRI Through Modeling And Imaging Microvascular Dynamics

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.
Radiological Features Correlating With Seizures In Patients With Supratentorial Gliomas

Summary
Gliomas are the most common brain tumours, with more than 1,500 new cases diagnosed in Australia each year. Around 50% of all glioma patients suffer from seizures, which are difficult to control with current anti-epileptic drugs. The epilepsy and the side-effects of the drug therapies are a major cause of morbidity and impaired quality of life. It is also a significant burden on the economy, leading to more and longer hospital admissions, and loss of productivity for both patients and carers.

Failure to reach these standards is associated with poorer outcomes in mental health and socioeconomic status, greater representation among the prison population and with failure to achieve to true ability. Further, failure to correct these problems may well result in transmission of the problems associated with failed literacy into the next generation. Despite the obvious immense social and personal ramifications and cost, literacy instruction for adults continues to lack a theoretical and research based approach . It is plain that improving population literacy would have significant benefits and it is also plain that early detection, intervention and remediation is desirable. This project brings to bear on these important aims current expertise in the nature of reading, how children learn to read and why some have so much difficulty in doing so, and techniques for determining the neural substrates of the mechanisms involved in reading and learning to read. We will subdivide child readers on the basis of their ability to read words using the letter to sound route or dictionary look-up route. We will use magnetic resonance imaging and spectroscopy to examine which parts of the brain are disrupted and-or disconnected when ability to read in either of these two routes is poor. We will then remediate these poor readers using targetted remediation therapy and re-image them to see whether remediation has altered the way the brain reads.Read moreRead less
Magnetic Resonance Imaging Of Structural And Functional Connectivity In Lesion-negative Temporal Lobe Epilepsy Compared To Hippocampal Sclerosis

Summary
Epileptic seizures in the temporal lobe of the brain can affect how the temporal lobe connects to other brain regions. We are using new MRI techniques to investigate these altered connections, in patients who have no other abnormality on their brain scans. Our aim is to find distinctive patterns of altered connectivity, which will help us better understand this type of epilepsy.
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.
