Enthesitis is the hallmark of spondyloarthritis. 23 patients with SpA and 13 healthy volunteers were studied with DCE-MRI of the tendon and the calcaneal bone marrow at the Achilles enthesis. The relative early enhancement rate was significantly greater in SpA patients than healthy volunteers. The EER was significantly higher in patients with power Doppler ultrasound abnormalities. Tendon and bone changes were significantly correlated (R=0.6). In conclusion, DCE-MRI may be useful for assessing changes at the Achilles enthesis in spondyloarthritis.
