Fig. 2From: Ultrasonography and dual-energy computed tomography provide different quantification of urate burden in gout: results from a cross-sectional studyDual energy computed tomography (DECT) and ultrasonography (US) provide different quantification of urate deposition. a Comparison of each individual tophus volume as measured by DECT (triangles) and US (squares). b Ratio of the volume measured with DECT and US for each individual tophus. c Volume of overall urate deposition measured by DECT according to the number of joints presenting with the US double contour (DC) signBack to article page
