Radiology can be a challenging subject for students and finding new techniques that help improve their understanding could have positive effects in their clinical practice. The purpose of this prospective experimental study was to implement the use of color-coded, three-dimensional-printed, handheld equine carpus models into a radiographic anatomy course and evaluate the impact objectively and subjectively using quizzes and student response surveys. A first-year veterinary class was randomly divided into two similarly sized groups (groups A and B) for an equine normal radiographic anatomy laboratory. Both groups experienced the same laboratory structure; however, each student in group B received a handheld three-dimensional-printed equine carpus. Both groups received a quiz at the end of their laboratory consisting of 10 multiple-choice questions related to the equine carpus. An anonymous survey regarding the laboratory was emailed to students after the laboratory. One week later, the same 10 questions in randomized order were administered via a pop-quiz. Students believed both quizzes would count toward their final course grade. There was no statistically significant difference in grades between groups on either quiz (P > .05). However, based on survey responses, group B students felt the carpus made the laboratory more enjoyable and improved their comprehension of the material, whereas group A students felt the carpus would have increased their enjoyment and improved their comprehension. The implementation of three-dimensional-printed anatomic models may be useful to enhance enjoyment and perceived comprehension of veterinary students; however, there is currently insufficient evidence to suggest these models improve academic performance.
