%X <B>BACKGROUND: </B>Catheter shaping is vital in cerebral aneurysm coil embolization; however, understanding three-dimensional (3D) vascular structures on two-dimensional screens is challenging. Although 3D-printed vascular models are helpful, they demand time, effort, and sterility. This study explores whether mixed-reality (MR) devices displaying 3D computer graphics (3D-CG) can address these issues.<BR><B>METHODS: </B>This study focused on magnetic resonance imaging (MRI) of seven cases of cerebral aneurysms. Head-mounted display (HMD) and spatial reality display (SRD) MR devices were used, and applications for 3D-CG display at a 1:1 scale and a 3D-CG control panel were developed. Catheters shaped using a 3D printer, HMD, and SRD were inserted into hollow models to assess their accessibility and positioning.<BR><B>RESULTS: </B>The concordance rate of the 3D printer and HMD groups in terms of accessibility to the aneurysm was 71.4 %, while that of the 3D printer and SRD group was 85.7 %, and that of the HMD and SRD group was 85.7 %. The concordance rates of positioning in the 3D printer and HMD groups, 3D printer and SRD groups, and HMD and SRD groups were 85.7 %, 85.7 %, and 100 %, respectively.<BR><B>CONCLUSIONS: </B>MR devices facilitate catheter shaping in cerebral aneurysm coil embolization and offer a time-efficient, precise, and sterile alternative to traditional 3D printing methods.
