Under Segmentation, the following paper is listed:
Domain-agnostic segmentation of thalamic nuclei from joint structural and diffusion MRI
Henry F. J. Tregidgo et al. 2023
This work does not actually use a diffusion model, but a straightforward 3D U-Net to segment brain structures.
The confusion is probably caused by the concept of Diffusion MRI. This sequence, simply put, tracks the direction and velocity of fluids (mostly water) moving around a given spatial location. Most often this is done in the brain as it's quite easy to keep in place with little to no patient movement. This lets you create these cool looking fiber tractography images, as fluid is more likely to move in parallel to the nerve bundles spread across your brain!
