Dr. Stieger-Vanegas received her veterinary degree from the University of Veterinary Medicine in Vienna, Austria in 1995. Prior to joining Oregon State University, She completed a doctoral thesis about gallbladder disease in dogs, completed a PhD focused on ultrasound imaging of tumor angiogenesis and using ultrasound to enhance the vascular permeability, and completed a combined diagnostic imaging residency at the University of Veterinary Medicine in Vienna, Austria and the Vetsuisse Faculty, University of Zurich, Switzerland in 2001. She is recipient of the Camden endowed Professor in Radiology. Her clinical research interests include cancer imaging, thoracic and abdominal CT imaging in small animals and New World camelids. She is specifically interested in developing better imaging protocols imaging the heart and gastrointestinal tract using computed tomography. Additionally, she is interested in developing skills in 3D printing of complex normal and diseased anatomic structures.

Rachel Pollard DVM, PhD, Dipl ACVR
Topic: How to perform CT lymphangiography

Dr. Pollard attended Washington State University for her Doctorate of Veterinary Medicine.  She then moved to New York for a 1-year internship at the Animal Medical Center.  Dr. Pollard moved to Davis, CA in 1997 to complete the 4-year residency in Diagnostic Imaging at the University of California, Davis.  She then completed a PhD in Comparative Pathology and is currently a Professor of Diagnostic Imaging at UC Davis.  Her areas of research focus primarily on quantitative imaging techniques using both contrast enhanced computed tomography and contrast enhanced ultrasound to evaluate tumor blood flow.  Additionally, she has a clinical interest in dynamic imaging techniques such as contrast fluoroscopy with a focus on swallowing disorders. Dr. Pollard is also a level 1 professional telemark ski instructor.
