Imaging of the Seronegative Spondyloarthopathies

摘要: The seronegative spondyloarthropathies are a diverse group of conditions most commonly affecting the axial spine, often presenting with back pain an inflammatory nature. primary unifying feature these disorders is sacroiliitis. distinction between subtypes spondyloarthritis based on genotype (HLA-B27 positivity as in ankylosing spondylitis), peripheral manifestations disease (psoriatic and reactive arthritis), factors such age, gender, comorbidity. Although radiography has long been used to diagnose spondyloarthropathies, advanced imaging magnetic resonance better able at their earliest stages monitor disease-modifying therapies.
