VIRIES Board of Directors

The activities of the Veterinary Interventional Radiology and Interventional Endoscopy Society are based upon the mission statement to advance the art and science of veterinary IR/IE and other image-guided procedures. Some of these activities are listed below.

  1. Share scientific abstracts including original investigations, retrospective and prospective clinical studies, and unusual cases
  2. Listen to invited medical doctors speak on their respective specialties
  3. Discuss diagnosis, management, and advances of veterinary IR/IE and other image-guided procedures.
  4. Discuss the future development of this sub-specialization in veterinary medicine including development of guidelines for those veterinarians wishing to perform these procedures
  5. Create consensus statements on behalf of the Society concerning veterinary training or disease-specific grading, complication classifications, outcome measurements, etc.
  6. Participate in and promote training laboratories to provide veterinarians with opportunities to further develop these advanced techniques
  7. The encouragement of its members to contribute to continuing education in veterinary IR/IE and to report in high quality veterinary journals.
  8. Create an opportunity for collaboration among veterinarians performing these procedures by creating cooperative groups to share in multi-institutional research studies to achieve large patient populations rapidly.
  9. Promote and encourage collaboration between human and veterinary medical fields.
  10. Develop and maintain VIRIES listserve and website to provide on-line videos, case discussions, webinars, and other resources for veterinarians interested in IR/IE
