Expand description
MP-PCA denoising for multi-volume data (e.g. multi-echo magnitude).
Random-matrix-theory denoising (Veraart 2016) that removes noise along the
volume dimension while preserving spatial edges. Applying [mppca_denoise]
to multi-echo magnitude before R2*/R2 fitting reduces relaxation-rate
variance without blurring structure.
