A/Prof Parsons is a post-doctoral researcher, whose work using magnetic resonance and CT imaging techniques to study stroke pathophysiology and new therapeutic approaches is internationally recognised. He has published a number of first author papers in prestigious international journals, three of which have been keynote publications in the high impact Annals of Neurology, each accompanied by an editorial. A/Prof. Parsons PhD thesis detailed the use of modern, multimodality MRI techniques in acute stroke, from which he published several first author papers in high-impact international journals. He had particular interests in the effects of thrombolysis on the ischaemic penumbra, showing that intravenous tPA salvaged significant brain tissue in this critical region and these benefits correlated with improved clinical outcomes.
A/Prof. Parsons has also demonstrated the ability to translate fundamental research in the laboratory and clinic into solutions with direct practical application that can be incorporated into clinical practice. He has experience in the re-design and evaluation of health systems, often a critical step in the implementation of complex therapies such as stroke thrombolysis. A/Prof Parsons led the development of an ambulance protocol in the Hunter Region for the rapid identification, pre-hospital notification, and rapid transport of potential thrombolysis patients to a specialist stroke centre. This protocol led to a substantial increase in patients treated with thrombolytic therapy in the Hunter and on the Central Coast.

He is a CI on a current NHMRC program grant - ‘Improving Stroke Outcomes: Attenuating Progression and Recurrence’. He is CIA on a current NHMRC patnership grant, relating to standardization and implantation of advanced CT imaging in acute stroke. He is on the Steering Committees of multi-centre stroke trials EXTEND and INTERACTII (and a CI on the NHRMC project grant for INTERACTII. A/Prof. Parsons has completed two NHMRC-funded projects as principal investigator. The first investigated CT perfusion in acute ischaemic stroke and provided the impetus to establish an internationally unique human stroke perfusion imaging library of over 400 patients. The project directly led to six original articles, and one invited review, which have been published in international peer-reviewed journals. The second was a multi-centre study (2008-2010) of a new thrombolytic agent tenecteplase versus the standard agent alteplase in acute stroke. This study used CT perfusion both for patient selection into the trial, and also to compare reperfusion and penumbral salvage between the two agents. Articles resulting from this study have been published in The New England Journal of Medicine, Brain, Stroke, and Neurology. On projects related to stroke imaging, A/Prof. Parsons is currently supervising three PhD Students (with two more PhD students recently completing, one post-doctoral student, one B Med Sci student, and a Clinical Stroke Fellow. A/Prof. Parsons established the Stroke Imaging Research Laboratory at John Hunter Hospital, and is Director of the University of Newcastle’s Stroke Research Program, which is one of the four major streams of the Translational Neuroscience and Mental Health Priority Research Centre. He is the current vice-President Stroke Society of Australasia and is the immediate past chairman of the Australasian Stroke Trials Network.
