Figure 2. Questionnaire Results About Conventional Imaging, 3-Dimensional (3-D) Prints, and Augmented Reality (AR) Holograms.

Surgeons scored the visibility of the 4 anatomical structures from 1 to 5 (1 indicates completely disagree; 2, disagree; 3, neutral; 4, agree; and 5, completely agree) for conventional imaging (magnetic resonance imaging [MRI] and/or computed tomography [CT]) and for the 3-D visualizations (3-D print and AR holograms), with results showing the comparison of means of 10 patients. Center lines indicate the medians; error bars, the interquartile ranges.

^aP < .01 compared with MRI/CT.

^bP < .001 compared with MRI/CT.
