Active and structural lesions of the sacro-iliac joints in spondyloarthritis
MRI gains importance in early diagnosis of spondyloarthritis as it detects active inflammatory and structural lesions well before radiographic changes become evident. A ‘positive’ MRI with bone marrow oedema of the sacro-iliac joint is a key criterion in current disease classification systems
How sensitive and specific are MRI features of sacroiliitis for diagnosis of spondyloarthritis
'Objective: 'To determine the sensitivity and specificity of MRI features of sacroiliitis in spondyloarthritis (SpA). 'Materials and methods': A retrospective study reviewed MRI of the sacroiliac (SI) joints in 517 patients with inflammatory back pain. Sensitivity, specificity, positive and negative likelihood ratios of active and structural lesions of sacroiliitis with final clinical diagnosis as golden standard was calculated. 'Results: 'MRI showed active inflammation in 42% of patients (bone marrow oedema (BMO) (41.5%), capsulitis (3.3%), enthesitis (2.5%)) and structural changes in 48.8% of patients (erosion (25%), fat infiltration (31.6%), sclerosis (32%) and ankylosis (7.6%)). BMO was the MRI feature with the highest sensitivity (65.1%) for diagnosis of SpA. Capsulitis (99%), enthesitis (98.4%), ankylosis (97.4%) and erosion (94.8%) had a high specificity for diagnosis of SpA, whereas BMO?(74.3%), sclerosis (75.8%) and fat infiltration (84.0%) were less specific. BMO concomitant with enthesitis, capsulitis or erosions increased the specificity. Concomitant presence of BMO and sclerosis or fat infiltration decreased the specificity. 'Conclusion: 'BMO is moderately sensitive and specific for diagnosis of SpA in patients with inflammatory back pain. BMO concomitant with enthesitis, capsulitis, ankylosis or erosion increases the specificity. Concomitant fat infiltration or sclerosis decreases the specificity for diagnosis of SpA. Of all lesions, erosion had by far the highest positive likelihood ratio for diagnosis of SpA
