With the tremendous growth of options in equine CT and MRI, it can be difficult to know when to use which modality.  Join us for what promises to be an exciting panel discussion with an international panel of world-leading experts with extensive experience in this field. The pros and cons of the various types of CT and MRI systems, including low field and high field MRI, cone beam and fan beam CT and standing sedated and anesthetized studies will be discussed.  The panel will cover what to expect from the information gained in these studies and how to best use it as part of your diagnostic toolbox. We will provide case examples to illustrate and discuss the merits, benefits and limitations of the modalities. There will be plenty of opportunity for questions and contributions from attendees in this lively debate.

Dr. Barrett is an associate professor of equine diagnostic imaging Colorado State University. Dr. Barrett's primary research and clinical interests are equine musculoskeletal imaging and comparative imaging, and she works closely with the equine surgery and sports medicine services. She is a founding partner of Inside information Radiology, a dedicated equine teleradiology service. She routinely speaks at equine veterinary meetings and is regularly involved in continuing education courses, including courses that draw an international audience. Dr. Barrett is dedicated to the advancement of the specialty of equine diagnostic imaging and is currently the president of an AVMA newly recognized subspecialty – ACVR-Equine Diagnostic Imaging.

Rachel is a highly experienced Sport Horse Clinician, who is based at Rossdales Diagnostic Centre. She joined our team in October 2019, having spent more than 20 years at the Animal Health Trust where she was responsible for the Equine MRI diagnostic service, ran the orthopaedic research group and provided a clinical service focused on imaging, poor performance and rehabilitation in sport horses.

Rachel graduated from University of Cambridge before specialising in equine surgery, undertaking an internship and surgical residency in the USA, becoming a Diplomate of the American College of Veterinary Surgeons. After 5 years in the USA, she returned to England as an equine surgeon at the University of Cambridge Veterinary School. She subsequently completed a PhD, investigating exercise-associated joint adaptation and injury in horses.

She has led many studies investigating sport horse training, injury and performance, including for British Dressage, British Eventing, British Equestrian Federation and the FEI. She has also published numerous articles on orthopaedic problems and advanced imaging in horses, contributed to a number of books and edited the standard text on Equine MRI.

Rachel also works for the British Equestrian Federation in various roles, from scientific advice to practical veterinary assessments with various GB squads. Rachel has been providing advice for the BEF World Class Programme since 2009 and has been integrally involved in the maintenance and preparation of numerous team horses for Championships and Olympic Games. She is an FEI treating veterinarian, has worked as a veterinary surgeon with the GB Dressage and Show jumping teams, including as a team vet, and was an official treating veterinarian at the 2012 Olympics.

Sarah Puchalski is a native of Roberts Creek, British Columbia, Canada, and grew up riding horses in the BC countryside, competing actively in 3-day eventing.  She obtained a B.S. in Biology from Simon Fraser University in Burnaby, BC and went to veterinary school in Saskatoon, Saskatchewan, where she graduated with distinction in 1999.  From Saskatoon, she moved to Pennsylvania as an intern/resident in field service sports medicine at the University of Pennsylvania’s New Bolton Center from 1999-2001.  From New Bolton Center, Dr. Puchalski entered a four-year residency in diagnostic imaging at the University of California, Davis.  She obtained board certification in the American College of Veterinary Radiology in 2004, passing the grueling examination on her first attempt. 

In 2005, Dr. Puchalski joined the faculty in diagnostic imaging in the Department of Surgical and Radiological Sciences, UC Davis School of Veterinary Medicine, as an Assistant Professor.  During this time, she divided her focus between didactic and clinical teaching, research, service to the school and clinical radiology.  In the classroom, she led the general large animal radiology course and was a co-instructor in the equine lameness and radiology course.  Her research interests predominantly surround the use of novel imaging techniques for the diagnosis of lameness conditions in equine athletes.   As she has gained experience in this field, she has developed an international reputation for her expertise.  Dr. Puchalski was awarded tenure at the University in 2012 and promoted to Associate Professor, and has authored scientific, educational and lay articles as well as contributed to numerous textbooks. 

Dr. Puchalski left the University in late 2013 to open her own practice as a diagnostic imaging consultant.  In the winter months she is based in Wellington, Florida at Palm Beach Equine Clinic and during the remainder of the year in Petaluma, California at Circle Oak Equine.  As a show jumper, competing actively in Wellington, Florida at the Winter Equestrian Festival and in Northern California, she understands the challenges of equine ownership and what may be needed to keep these athletes sound.
