filter selection for DenoiseImage

[md06451]

Dear all,
I aim to use DenoiseImage to denoise the fast spin echo t1w scans (11 slices).
I read the paper based on which the algorithm is based https://doi.org/10.1002/jmri.22003 from Manjon. While they direct the reader on the selection of Rician filter for T2w, they do not write what we should choose for t1w scans. I see that the default settings in DenoiseImage is Gaussian and Gaussian was also used in an application of the Longitudinal Mapping of Cortical Thickness pipeline of with T1w (https://pmc.ncbi.nlm.nih.gov/articles/PMC10204115/; https://github.com/ANTsX/ANTs/blob/master/Scripts/antsLongitudinalCorticalThickness.sh). However, other studies (Coupe, 2011; 10.1016/j.neuroimage.2010.09.018) used Rician for t1w. What is your advice? which filter should I use? Thank you in advance.

In all of our early exploration, we tended to prefer the Gaussian results, in particular for T1-w images which is why that's the default. That's what I would recommend to you although, ultimately you should do the comparisons yourself and see which one best suits your purposes.
