Detection, scoring and volume assessment of bone erosions by ultrasonography in rheumatoid arthritis: comparison with CT
Annals of Rheumatic Diseases,  Clinical Article

Dohn UM et al. – In accessible areas, ultrasonography (US) was highly accurate for detection and semiquantitative assessment of rheumatoid arthritis (RA) bone erosion. Even the smallest erosions, only detected in one plane, were generally confirmed by CT.

Methods
  • The 2nd–5th MCP joints of 49 patients with RA were examined by CT and US, and evaluated for the presence of bone erosion in each MCP joint quadrant.
  • On CT, erosion volume was scored according to the OMERACT–RAMRIS score (bone volume loss in 10% increments of original bone volume).
  • US erosions were scored 0–3 according to the Szkudlarek and Scoring by UltraSound Structural erosion (ScUSSe) systems, respectively.

Results
  • Seven hundred and eighty–four MCP joint quadrants were examined.
  • Erosions were detected by CT in 259 quadrants and by US in 142 quadrants.
  • Sensitivity/specificity/accuracy of US was overall 44%/95%/78% compared with 71%/95%/90% in areas with good US accessibility (radial 2nd MCP, ulnar 5th MCP and all dorsal/palmar aspects).
  • US detected 95% of erosions with bone volume loss >20%.
  • In US accessible areas, 63% of erosions with 1–10% bone volume loss and 94% of erosions with >10% bone loss were detected.
  • The two US scoring systems agreed well on large erosions, whereas the smallest erosions (Szkudlarek grade 1, of which 86% were confirmed by CT) were not scored by ScUSSe.
