Classification criteria for spondyloarthropathies

Figure 2 Inflammatory changes and structural damage on spinal magnetic resonance imaging. A: T1-weighted fast spin echo sagittal magnetic resonance scan of the lumbar spine shows hypointense lesion on end plates of thoracic 11 and 12 vertebrae; B: T2-weighted fat suppressed sagittal image shows hyperintense signals at the lesion and also at the upper anterior of the L3 and lower anterior of L2 vertebra; C: T1-weighted post-contrast images shows enhancement of the contrast media at the borders of the lesion revealing acute spondylodisciitis.
