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.
Cerebral Blood Flow During Psychogenic Non-epileptic Seizures.

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.
Episodic Memory Dysfunction As A Basis For Auditory Hallucinations In Schizophrenia

Summary
Auditory hallucinations (AHs) occur frequently in people who suffer from schizophrenia. This symptom usually involves hearing voices that the hallucinator firmly believes originate from other people. The voices are often intrusive, abusive and persecutory. They are a source of significant stress and may result in self harm or harm to others. Our investigations will attempt to provide experimental support for the theory that AHs represent a misremembering of voices which were heard in the past.

This symptom usually involves hearing voices that the hallucinator firmly believes originate from other people. The voices are often intrusive, abusive and persecutory. They are a source of significant stress and may result in self harm or harm to others. Our investigations will attempt to provide experimental support for the theory that AHs represent a misremembering of voices which were heard in the past. We will do this by attempting to characterise specific problems that hallucinators have in identifying when they heard verbal fragments and who said them. We plan to conduct our investigations at five levels. First, we will determine how accurate hallucinators' memories are for context by the use of special neuropsychological tests. Second, we will find out if hallucinators form more false memories than comparison subjects using a test in which such incorrect recollections occur commonly. Third, we will determine if hallucinators have a tendency to reconstruct the characteristics of false verbal memories in the same way that they reconstruct the characteristics of their hallucinations. Fourth, we will attempt to suppress these false verbal memories and finally, we will characterise those brain regions which are activated during true and false memory formation by using blood flow analysis technology in order to identify networks of brain activity which preferentially malfunction in hallucinating patients. This study provides the prospect of adding substantially to our understanding of the mechanisms underlying auditory hallucinations and to lead to the development of new cognitively-based treatments for the symptom.Read moreRead less
Atherosclerotic Plaque Imaging With High Resolution MRI / Multi-Detector CT / PET

Summary
Diseased blood vessels often involve build up of cholesterol plaques that cause blockages or poor blood flow. This can lead to strokes and heart attacks. Our research aims to investigate the properties of diseased vessels in the neck with the latest scanning technologies to identifying individuals who are at risk of strokes. We hope to show that the inflammatory activity and composition of the plaques play important roles in leading to the development of strokes.
