MR imaging at 1.5T vs 3T have different advantages. 🧠
Aside from cost considerations, imaging at 3T delivers higher signal to noise (SNR) enabling increased spatial resolution, critical for identification of smaller white matter tracts and changes that may result from injury or disease.

A post on visualizing white matter bifurcations using diffusion analysis:
🧠
We show that using the diffusion model and seed-based #tractography, we are able to delineate the full bifurcating module of a bifurcating module in our phantom POP-0005 with dimensions as given.
