20.500.12556/DiRROS-30704 Discrepancies between routine sacroiliac joint MRI reporting and current expert recommendations in patients with spondyloarthritis Background Sacroiliac joint (SIJ) MRI is commonly used in diagnosing spondyloarthritis (SpA). Current Assessment of SpondyloArthritis International Society (ASAS) recommendations on reporting SIJ MRIs in patients with known or suspected axial SpA recommend always stating whether bone marrow oedema (BME), erosions and fat lesions are present/absent and whether the MRI is compatible with axial SpA. Purpose To investigate if routine care radiologists already report what has now been recommended and to assess the agreement between local radiologists and central SpA experts. Materials and methods This study includes retrospective interpretation of images acquired in routine care. Patients diagnosed with SpA enrolled in a clinical registry in one of five European countries involved in the EuroSpA Collaboration, with an available SIJ MRI and an associated local MRI report, were included. MRIs were read centrally by two readers, who registered global features (eg, MRI indicative of SpA), and various inflammatory and structural lesions as present/absent. Similar information was extracted from local reports. Findings were analysed with descriptive statistics. Results Overall, 913 patients (40 years±13, 492 men) were included. In 24%, the local MRI reports stated whether the MRI was overall indicative of SpA or not. Presence/absence of BME, erosions and fat lesions was mentioned in 88%, 48% and 29% of local reports, respectively. Inflammatory lesions were more often reported as present by local than central readers (46% vs 36%), and structural lesions less often (33% vs 50%). Conclusion This study demonstrated a large gap between the clinical practice of reporting SIJ MRIs and recent reporting recommendations. magnetic resonance imaging psoriatic arthritis spondyloarthritis true false true Angleški jezik Ni določen Neznano 2026-07-01 11:02:31 2026-07-01 11:02:31 2026-07-03 03:46:47 0000-00-00 00:00:00 2025 0 0 Nasl. z nasl. zaslona; Opis vira z dne 16. 6. 2026; str. 1-10 issue 4, [article no,] e006316 Vol. 11 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 616.72:615.849 2056-5933 10.1136/rmdopen-2025-006316 281724931 RAZ_Enevold_Floistrup_Hadsbjerg_Anna_2025.pdf RAZ_Enevold_Floistrup_Hadsbjerg_Anna_2025.pdf 1 1B26E6C2F548AF6FC1AB83CB9D6BADF5 e507f76e5bc1d501aa6ea0552c65391561b2af698824e49fe6b62db88bf9b836 139b61f1-75f4-11f1-a2b4-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=47027 https://rmdopen.bmj.com/content/11/4/e006316 1 992ed484-752b-11f1-b0d9-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=46837 Univerzitetni klinični center Ljubljana 0 0 0
