The optic radiation (OR), is often severed during temporal lobe resection, resulting in permanent quadrantanopia. To date all published tractography methods that delineate the OR require manual input (e.g. region-of-interest placement and adjustment), or appear to underestimate Meyer’s Loop, limiting their widespread clinical adoption. Here, we present and validate the CONSULT pipeline for OR delineation. This pipeline accepts unprocessed DICOM images as input and produces realistic subject-specific segmentations of the OR, including Meyer’s Loop, without need for any human input. Its validation in 183 datasets demonstrated plausible delineations that are in line with previous dissection studies.
