  • For synovitis (according to the RAMRIS score), tenosynovitis of the flexor tendons and peritendonitis of the extensor tendons, the sum scores are given as absolute numbers and SD. The share of positive findings (score >0) is listed in per cent of joint groups/patients.

  • *The total sum scores correlated with a Pearson’s r of 0.94.

  • MCP, metacarpophalangeal; PIP, proximal interphalangeal; ULD-CT, ultra-low-dose CT; mRAMRIS, modified Rheumatoid Arthritis MRI Score.
