a distribution of the 5-points rating in the overall clinical evaluation data set and different diseases. A nonparametric test was used for comparing two groups. b Comparison between AI and manual processing in VR and MIP. a Right middle cerebral artery is occlusive without reconstruction of collateral circulation in manual processing, while AI successfully reconstructed the collateral circulation (b). The VR was cleaner in AI than the manually processed image, especially in cavernous sinus segments (c, d). e–g The standard for evaluating the MIP in the manually processed image and h was generated by CerebralDoc for the same patient as g without bone residual.
