21st Annual

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. 

After a COVID-19 related hiatus in 2020, we have decided to hold the 2021 Symposium as a Hybrid Conference – ie both online for those who can not or don’t feel safe yet to travel and, if local health policies allow for it – onsite for those who want to come to Toronto to meet friends and colleagues 

Similar 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. 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 theme of the symposium highlights Vessel Wall Imaging and its role in our field while both the Stroke and Aneurysm topics will be presented through 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. 

We are looking forward to welcoming you to Toronto in 2021 – either online or onsite!

For the Organizers,

Timo Krings



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.

The 21st Interventional Neuroradiology Symposium & 6th Annual Karel G terBrugge Lectureship & Neurovascular Anatomy Workshop will be applied for accreditation as an Accredited Group Learning Activity (Section 1), defined by the Maintenance of Certification (MOC) program of the Royal College of Physicians and Surgeons of Canada (RCPSC). Previous similar programs have been approved by the Canadian Association of Radiologists (CAR) for a maximum of 19.5 credit hours.

Through an agreement between the Royal College of Physicians and Surgeons of Canada and the American Medical Association, physicians may convert Royal College MOC credits to AMA PRA Category 1 Credits™. Information on the process to convert Royal College MOC credit to AMA credit can be found at www.ama-assn.org/go/internationalcme
