Comparison of questionnaire scores for various anatomical structures between conventional MRI images (Blue) and AR-based 3D models (Red). Two surgeons independently rated the visibility of 6 anatomical structures using a scale from 1 to 5 (1 indicating strongly disagree; 2, disagree; 3, neutral; 4, agree; and 5, strongly agree) for both conventional MRI images and AR-based 3D models. The results represent the comparison of mean scores from eight patients, with the middle lines indicating the medians
