Table 1 Baseline data on inflammation and occurrence of definite radiographic damage as assessed by both magnetic resonance imaging sequences

From: The relationship between inflammation and new bone formation in patients with ankylosing spondylitis

MRI sequence Inflammation/radiographic damage Proportion (number) of vertebral edges at baseline P value
STIR Any inflammatory lesions 16.6% (153/922) -
  No inflammatory lesions 83.4% (769/922)  
  Definite radiographic damage with inflammation 17.6% (27/153) 0.53
  Definite radiographic damage without inflammation 15.6% (120/769)  
T1-post-Gd Any inflammatory lesions 10.3% (95/922) -
  No inflammatory lesions 89.7% (827/922)  
  Definite radiographic damage with inflammation 21.1% (20/95) 0.13
  Definite radiographic damage without inflammation 15.1% (125/827)  
  1. There was no difference in the proportion of inflammatory lesions and occurrence or absence of syndesmophytes at baseline. MRI, magnetic resonance imaging; STIR, short-tau-inversion-recovery; T1-post-Gd, T1-post-gadolinium.
