Abstract WP248: Enhancing Neurovascular Education Through 3D-Printed Models: A Pilot Study in Neurology Training

Background: Accurate treatment decisions in acute ischemic stroke hinge on nuanced knowledge of neurovascular anatomy. Yet, many trainees still miss key findings, highlighting the need for stronger neurovascular education. We hypothesized that supplementing traditional lectures with 3D-printed models may improve retention and recognition of intracranial arterial anatomy in trainees. Methods: We conducted a single-institution pilot trial comparing traditional lecture-based instruction with adjunctive 3D model use in teaching neurovascular anatomy ( Figure 1 ). Neurology residents, radiology residents, and medical students were randomized to either control or 3D groups during two sessions (2024, 2025). Participants completed pre- and post-intervention assessments testing vessel identification on various imaging modalities and in various orientations. Mixed-effects models were used to analyze score changes, with fixed effects for time (pre vs. post-lecture), instructional modality (control vs. 3D), learner type, and interaction terms. Likert scale surveys were offered to assess trainee satisfaction. Results: Both groups demonstrated significant improvement from pre- to post-test (F=40.3, p
