Figure 1.

Anatomical images from a 71-year-old female were used for testing the deep learning model to segment the choroid plexus (a–d: T₁,: e:T₂-FLAIR). A 3-D U-Net architecture was employed to produce 3-D choroid plexus segmentations (f–j). T₁-weighted images have been windowed specifically to show contrast between choroid plexus and ventricles, rather than gray and white matter.
