Correspondence on 'Ultrasound shows rapid reduction of crystal depositions during a treat-to-target approach in gout patients

With great interest, we read the article by Hammer et al reporting a treat-to-target (T2T) approach with urate-lowering treatment (ULT) resulted in significant reductions of crystal depositions via ultrasonic detection.1 We agree with the authors that the use of new semiquantitative scoring system may increase the sensitivity to minor changes in lesions in contrast to a binary scoring system. We would like, however, to highlight some key points.
