Bland Altman for SURhotspot/cortex and SURhotspot/mirror analysis. Mean bias for maxSURhotspot/cortex (left) and maxSURhotspot/mirror (right) respectively in the overall (a, b), metal (c, d) and non-metal (e, f) subgroup. ZTE–AC and atlas-AC compared to reference standard CT-AC. Bars and whiskers are mean ± SD. Despite atlas-AC showed narrower mean bias range -closer to zero- in the metal subgroup, ZTE–AC presented narrower SD and 95% CI for all the three groups, metal subgroup included. No notable difference in AC compared to CT-AC was found for both methods
