Synopsis

Keywords: Vessels, Inflammation, synovitis;Pannus;Wrist jointIn this paper, 18 cases of wrist magnetic resonance enhancement were collected, a pixel-by-pixel time-intensity curves (TIC) analysis method was proposed, four types of enhancement curves were customized, and compared with the synovitis score, the results showed that the area of the rapidly rising and descending pixel area was extremely correlated with the synovitis score (r=0.812).
