Carpal depressions are commonly observed in healthy children and in patients with JIA. The aim of our study was to further characterize these depressions in patients with JIA.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods.<\/jats:title><jats:p>A total of 29 MRI wrist examinations were analyzed. Depressions were classified according to morphology as either tubular or focal. Features including the presence of a vessel related to the depression, evidence of synovitis, bone marrow edema, or loss of joint space on a radiograph taken on the same day were recorded for each depression.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results.<\/jats:title><jats:p>A total of 173 depressions were identified in 145 carpal bones. Forty percent were capitate depressions. A third were focal depressions and two-thirds were tubular. About 10% of tubular depressions and 30% of focal depressions were associated with features suggesting true erosions, with the remainder likely to represent vascular channels and normal variants.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion.<\/jats:title><jats:p>Radiologists and clinicians should undertake caution when assessing carpal depressions on MRI because the vast majority are likely to represent normal variants.<\/jats:p><\/jats:sec>","DOI":"10.3899\/jrheum.110445","type":"journal-article","created":{"date-parts":[[2012,2,2]],"date-time":"2012-02-02T18:58:39Z","timestamp":1328209119000},"page":"645-650","source":"Crossref","is-referenced-by-count":18,"title":["Magnetic Resonance Imaging and Radiographic Assessment of Carpal Depressions in Children with Juvenile Idiopathic Arthritis: Normal Variants or Erosions?"],"prefix":"10.3899","volume":"39","author":[{"given":"PETER","family":"BOAVIDA","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"RIKIN","family":"HARGUNANI","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"CATHERINE M.","family":"OWENS","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"KAREN","family":"ROSENDAHL","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2262","published-online":{"date-parts":[[2012,2,1]]},"reference":[{"key":"2018112909275583000_39.3.645.1","unstructured":"Cassidy JT Petty RE Laxer RM Lindsley CB .
