We read with great interest the recent publication by Sahlein et al,1 describing thought-provoking data on a small number of aneurysms undergoing routine imaging surveillance that went on to rupture. These aneurysms had been followed with non-invasive neurovascular imaging and were believed to have remained stable in size and morphology on review by an experienced multidisciplinary group at a high volume aneurysm center. The patient images were retrospectively analyzed by Rapid Aneurysm (RapidAI, Menlo Park, CA), a semi-automated segmentation software, rendering discernable and quantifiable volume increases that had escaped the human eye. These findings beg the clinically relevant question: Can routine artificial intelligence (AI) interpretation of aneurysm surveillance imaging better guide medical decision-making to prevent ruptures and their significant sequelae? Conversely, can AI also avoid false positive interpretations of aneurysm growth that lead to unnecessary anxiety or treatment?
