T1w MRI vs STIR MRI vs Conventional Radiography in Evaluation of Seronegative Spondyloarthropathies

Ankylosing spondylitis and other seronegative arthropathies are conventionally diagnosed using clinical criteria and xrays of SI joints and spine. The introduction of MRI particularly the STIR sequence has revolutionised the diagnosis and assessment of activity of the diseease. But as inferred from this study MRI is not infallible and xrays maybe superior to MRI to identify the structural changes and low dose CT maybe a good alternative to even MRI to establish the Diagnosis.
