Show abstract
Assessment of intrinsic tissue integrity is commonly accomplished via quantitative relaxometry or other specialized imaging, which requires sequences and analysis procedures not routinely available in clinical settings. We detail an alternative technique for extraction of quantitative tissue biomarkers based on intensity normalization of T1- and T2-weighted images. We develop the theoretical underpinnings of this approach and demonstrate its utility in imaging of multiple sclerosis.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
