Summary
Asthma is a common disease which is typified by excessive narrowing of the airways in response to stimuli that are trivial to non-asthmatic individuals. However, little is known about what causes asthmatic airways to be able to narrow so excessively. In this study, we will be looking at the importance of thickening of the airway walls in relation to excessive airway narrowing in asthmatics. We will also look to see how patchy the airway narrowing is in asthmatics and how this relates to excessiv ....Asthma is a common disease which is typified by excessive narrowing of the airways in response to stimuli that are trivial to non-asthmatic individuals. However, little is known about what causes asthmatic airways to be able to narrow so excessively. In this study, we will be looking at the importance of thickening of the airway walls in relation to excessive airway narrowing in asthmatics. We will also look to see how patchy the airway narrowing is in asthmatics and how this relates to excessive airway narrowing that occurs in severe asthmatic attacks. We will therefore be studying asthmatics of varying degrees of disease severity as well as those admitted to hospital because of acute severe attacks of asthma, and comparing them with a group of non-asthmatic subjects.Read moreRead less
The Effect Of Statin And Colchicine On Pericoronary Adipose Tissue Inflammation And Coronary Artery Plaque Progression: Insights From Cardiac Computed Tomography Using Pericoronary Adipose Tissue Attenuation And Radiomics

Summary
Coronary artery disease is the leading cause of death in Australia. Inflammation is a key driver of harmful build-up of cholesterol plaques in arteries. Currently it is unclear how to detect patients with high level of inflammation. We examine a new approach to detect coronary inflammation using CT coronary angiography (CTCA). We investigate how to utilise CTCA to guide targeted therapy with statin and colchicine in patients with residual inflammation to reduce risk of future heart attack.
Breast Arterial Calcification And Cardiovascular Disease – Exploring Mechanisms And Outcomes.

Summary
Heart disease remains the major of cause of death in women in the Western world and current methods of screening women for heart disease are out-dated and inaccurate. Calcification in the breast arteries that can be diagnosed on screening mammograms has been associated with future heart disease. This may represent a unique way to screen and treat patients for heart disease without the need for additional testing and our research program aims to investigate this.

Summary
Obesity is a major risk factor for cardiovascular disease and death. This project will investigate the links between obesity, heart attacks and abnormal heart function and the impact of weight loss on these detrimental effects in patients who have had a heart attack. This research aims to better understand mechanisms that may prevent future heart attacks and improve heart function.
The Role Of New Generation Multidetector Row CT For Identification And Management Of Vulnerable Plaque At Risk Of Acute Coronary Syndrome : A Prospective Observational And Interventional Study

Summary
Heart attack remains one of the major cause of death. This is usually due to rupture of a plaque (due to cholesterol buildup) in the major heart arteries. Studies using invasive ultrasound have identified some features of plaque that are at high risk of rupture. These plaques are referred to as "vulnerable plaque". Recent developments in the computed tomography (CT) technology which is a non-invasive technique has enabled us to also identify these features. However thus far, no prospective large
Very Fast, Accurate And Low Dose Imaging For Radiotherapy Treatments

Summary
This project will reduce scan times and imaging dose by an order of magnitude for an imaging modality that is the standard of care for lung cancer patients receiving radiotherapy. Specifically, scan times reduce from 4min to below 60sec, image quality will be improved and imaging dose will be reduced by 85%. These improvements not only improve treatment efficacy by improving the accuracy of radiotherapy delivery, they reduce treatment times and reduce discomfort to the patient.
Risk Stratification And Early Interventions In Pulmonary Vascular Disease: From Acute Pulmonary Embolisms To Chronic Pulmonary Hypertension

Summary
Pulmonary embolism (PE) is a common, potentially life-threatening condition with up to 50% of survivors developing long-term complications, which are associated with breathlessness, functional limitation and risk of premature death if not diagnosed and treated promptly. This project investigates the use of non-invasive scan techniques and exercise testing for early detection of these complications. The project will also explore new drug targets to treat these complications.
The Influence Of Transcatheter Aortic Valve Implantation On Myocardial Structure And Function

Summary
Transcatheter aortic valve implantation has given options to elderly patients who were previously faced with an open-heart operation. Our research utilises CT scans to determine the anatomical and physiological effects this new technology has on the heart. This research will help to guide the ongoing development and refinement of this technology. The research has the potential to revolutionise how aortic stenosis is assessed and timing of intervention is determined.
