Interventional Neuroradiology Symposium

& 6th Annual Karel G. Terbrugge Lectureship & Neurovascular Anatomy Workshop

***NEW DATES*** - September 17-19, 2021 – BMO Education & Conference Centre, Toronto, CA

Co-Organized by the Department of Medical Imaging, University of Toronto and the Department of Diagnostic Imaging, Hospital for Sick Children (SickKids)

Welcome Address


We are happy to invite you to the 21st Edition of our INR Symposium together with the 6th Annual Terbrugge Lectureship and Neurovascular Course.

2020 marks the first year in over 20 years in which we were not able to hold our symposium – given the continued high prevalence of Covid-19 cases in many parts of North and South America. The Organization Committee of the INR Symposium has made the decision to therefore postpone the 2020 Interventional Neuroradiology Symposium and the Karel Terbrugge Lectureship to 2021. 

One of the main goals of our symposium has been and will continue to be that we bring together friends and colleagues from all over Canada and the US – this “social” component of the INR symposium is currently incompatible with the need for physical distancing. 

We hope that in 2021, things will have calmed down and we will be able to see each other in person. 

In correspondence to previous years we will again start our 3 day Symposium with a full day of Neurovascular Anatomy that this year focusses on the neurovascular anatomy of the posterior fossa. In addition to lectures we will have case-based and disease centered lectures highlighting why neurovascular anatomy is important in the treatment planning of diverse diseases within this region ranging from aneurysms, stroke, stenosis, AVM to dural AV fistulae and dissections. 

The second day will highlight recent advances in Neurointervention – such as AI, Robotics, fMRI for planning of functional stereotactic procedures or the broadening of our neurointerventional scope towards subdural hematomas and facial vascular malformations. The Neuroimaging portion of our symposium highlights Vessel Wall Imaging and its role in our field while both the Stroke and Aneurysm portions will be heavily based on Debates and Case presentations. In addition we will discuss spinal percutaneous procedures and their current evidence. The Karel Terbrugge Lectureship will be awarded to Dr.Josh Hirsch from Boston, USA who will speak about the economics and cost-effectiveness in our field. 

Similar to last year we will seek endorsement by SNIS and SVIN and we believe the Symposium and its associated workshop will be of interest to a broad audience of Neurosurgeons, Neurologists, Neuroradiologists, and Interventionalists. 

We are looking forward to welcoming you to Toronto in 2021 – until then: Stay safe!


Please note that this program was developed following a review of objective data including practice data, literature surveys/reviews, consultation with experts in the field, and the experience and needs perceived by members of the planning committee. As well, subjective data from the previous year’s evaluations was reviewed in detail to create a focus for this year’s program.
