Magnetic resonance imaging is the most relevant tool for the early detection of sacroiliitis, allowing the institution of therapeutic strategies to impede the progression of the disease. This study illustrates the major criteria for a magnetic resonance imaging-based diagnosis of spondyloarthropathy. The cases selected here present images obtained from the medical records of patients diagnosed with sacroiliitis over a two-year period at our facility, depicting the active and chronic, irreversible forms of the disease. Although computed tomography and conventional radiography can also identify structural changes, such as subchondral sclerosis, erosions, fat deposits, and ankylosis, only magnetic resonance imaging can reveal active inflammatory lesions, such as bone edema, osteitis, synovitis, enthesitis, and capsulitis.<\/jats:p>","DOI":"10.1590\/0100-3984.2015-0211","type":"journal-article","created":{"date-parts":[[2017,7,22]],"date-time":"2017-07-22T23:35:32Z","timestamp":1500766532000},"page":"258-262","source":"Crossref","is-referenced-by-count":7,"title":["Spondyloarthropathy: diagnostic imaging criteria for the detection of sacroiliitis"],"prefix":"10.1590","volume":"50","author":[{"given":"Moacir Ribeiro de","family":"Castro Jr.","sequence":"first","affiliation":[{"name":"Universidade Federal de S\u00e3o Paulo,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sonia de Aguiar Vilela","family":"Mitraud","sequence":"additional","affiliation":[{"name":"Universidade Federal de S\u00e3o Paulo,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marina Celli","family":"Francisco","sequence":"additional","affiliation":[{"name":"Cl\u00ednica IMED - Cl\u00ednica M\u00e9dica e Diagn\u00f3stico por Imagem,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Artur da Rocha Corr\u00eaa","family":"Fernandes","sequence":"additional","affiliation":[{"name":"Universidade Federal de S\u00e3o Paulo,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eloy de \u00c1vila","family":"Fernandes","sequence":"additional","affiliation":[{"name":"Universidade Federal de S\u00e3o Paulo,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"530","published-online":{"date-parts":[[2017,7,24]]},"reference":[{"key":"ref1","doi-asserted-by":"crossref","first-page":"1218","DOI":"10.1002\/art.1780341003","article-title":"The European Spondylarthropathy Study Group preliminary criteria for the classification of spondylarthropathy","volume":"34","author":"Dougados M","year":"1991","journal-title":"Arthritis Rheum"},{"key":"ref2","doi-asserted-by":"crossref","first-page":"747","DOI":"10.1016\/j.berh.2011.02.002","article-title":"Seronegative spondyloarthritis","volume":"24","author":"Zochling J","year":"2010","journal-title":"Best Pract Res Clin Rheumatol"},{"key":"ref3","doi-asserted-by":"crossref","first-page":"340","DOI":"10.1590\/S0482-50042006000500007","article-title":"Medidas de avalia\u00e7\u00e3o cl\u00ednica em pacientes com espondilite anquilosante.
