TOPLINE:

The analysis of structural lesions in sacroiliac joints using MRI showed distinct patterns of structural changes across multiple groups, with patients with axial spondyloarthritis (axSpA) showing higher rates of erosions and fatty lesions than other groups without axSpA. Inflammatory and structural lesions occurred simultaneously in those with axSpA.

METHODOLOGY:

Researchers assessed differences in the structural lesions appearing on sacroiliac joint MRIs in 172 participants (mean age, 30.1-34.3 years) from two projects comparing patients with axSpA with those without.

They included patients with axSpA (n = 47) and those without axSpA comprising patients with chronic back pain (n = 47), women with postpartum back pain (n = 7), runners (n = 24), and healthy individuals (n = 4
