Residencies and Internships

The residency program is designed to provide high-quality, in depth clinical training in the areas of veterinary diagnostic imaging which will adequately prepare the resident to pass the examination for the ECVDI/ACVR diploma. The program will provide and in-depth understanding of diagnostic radiology, ultrasonography, computed tomography and magnetic resonance tomography as well as knowledge of the general principles and applications of nuclear medicine. The principles of radiation safety and biology and radiotherapy will be given. Residents will rotate through radiology/ultrasound/CT/MRI. The focus of the residency will be on small animals and equine patients; however experience will also be gained with food animals and exotic species. Learning activities scheduled on a weekly basis include imaging rounds, pathology rounds, journal club, resident seminar series, and examination preparation. The resident is expected to complete a clinical research project during the second year. Further information about the program can be found on the ECVDI or ACVR website.
