ac Dorsal longitudinal MSUS dorsal scan of radiocarpal joint in two different RA patients. a Gray-scale dorsal longitudinal musculoskeletal ultrasonographic scan of a 2nd metacarpophalangeal joint (m: metacarpal bone, p: proximal phalanx) shows synovial hypertrophy (black arrow) grade 2 and an erosion (e) in RA patient with increased serum CXCL13 level of 120 pg/ml. b Grey-scale dorsal longitudinal midline musculoskeletal ultrasonographic scan of the wrist joint (radiocarpal and midcarpal joints) of the same patient shows an erosion (arrow) in the lunate bone (r: radius bone, L:lunate bone, C: capitate bone). c Dorsal PDUS longitudinal midline musculoskeletal ultrasonographic scan of a wrist joint (radiocarpal and midcarpal joints) (r: radius bone, L: lunate bone, C: capitate bone) shows severe synovitis marked by synovial hypertrophy grade 3 and power doppler activity grade 3 in RA patient with increased serum CXCL13 level of 803 pg/ml. CXCL13: serum B lymphocyte chemoattractant protein13. PDUS power doppler ultrasound
