Hi all,

I was wondering if anyone could give me some advice on whether or not to denoise DTI data. In DTIPrep (an extension through Slicer), you can either do a Rician LMMSE and/or a Joint Rician LMMSE on the DTI data on top of another of quality control steps (eddy current correction, epi distortion corrections......which I have done). I am sure this is largely dependent on the quality of the data, but are there any cons to applying a denoising procedure? If it is good to use denoising, is it better to do the Rician LMMSE or the Joint Rician LMMSE?

Thanks and I appreciate any advice anyone has!

Emily
