Example T1-weighted sequence from a 53 year old male with mild cognitive impairment (a–d) and manual tracings (e–f) utilized in training of the machine learning methods. Example outputs from the T1-weighted trained machine learning model (g–h) are shown compared to FreeSurfer segmentations (i–j). Dice scores are shown for machine learning and FreeSurfer outputs and reflect an improvement in segmentation accuracy for the proposed method
