Review for NeurIPS paper: MRI Banding Removal via Adversarial Training

Weaknesses: - The dithering method used for comparison purpose has been optimized using the feedbacks of a single radiologist. The authors stated that adding extra noise is more effective for banding artefact removal but could lead to artefact details suppression. It would have been interesting to compare the proposed approach with the dithering method with two different levels of noise in order to back up this claim. Using standard monitors it is quite complicated to spot differences in the different approaches, and without radiologist expertise it is impossible to rate the different techniques. Does that not suggest that the problem is not so significant (given the high prevalence of 3T clinical scanners?
