Professor Aviv has authored over 130 peer-reviewed publications and contributed to several neuroradiology textbook chapters. He was awarded the 2010 Young Investigator award from the Canadian Association of Radiologists. His research interests are broad and include intracerebral hemorrhage, advanced stroke imaging and Multiple Sclerosis (MS). Funding sources include the Canadian Institute of Health Research, HSF, Multiple Sclerosis Society and PSI. Professor Aviv coined the term CTA Spot sign and has published widely on the definition, limitations and natural history of the sign. Professor Aviv is involved with several prospective international studies utilizing the CTA spot sign to select patients for medical therapy. He has developed a novel animal model of intracerebral hemorrhage and extravasation, which facilitates the testing of existing and novel therapeutic interventions. Professor Aviv is also particularly interested in the link between Gray matter perfusion abnormality and cognition in MS. MRI perfusion facilitates a greater understanding of the underlying pathophysiology of MS and provides a potential biomarker of disease severity.
