FreeSurfer segmentation (green = right hemisphere, blue = left hemisphere) of the entorhinal region of interest superimposed on a sum image (60 minutes) of [11C]-docosahexaenoic acid ([1-11C]-DHA) and T1-weighted magnetic resonance imaging scans of one participant. DHA incoporation coefficient k* in the entorhinal cortex is illustrated in the red rectangles
