High-resolution T2-weighted MRI has been shown to be a promising modality for imaging the subfields of the hippocampal formation. However, until now, the analysis of this data required tedious manual segmentation. We present a reliable method for automatic segmentation of hippocampal subfields in T2-weighted MRI and apply it to measure group differences in subfield volume and thickness between amnestic MCI patients and controls.
