Aktif Sakroiliitin Manyetik Rezonans Görüntülemesinde Gözlemciler Arasındaki Uyum

Abstract

Amaç Aksiyal spondiloartropatiler entezit, sakroileit ve spondilit gibi karakteristik klinik özelliklere sahiptir, ayrıca eklem dışı belirtiler de görülebilir. Sakroiliak (SI) eklem manyetik rezonans görüntülemesi (MRG), erken sakroileiti tespit etmek için kullanılır. Bazen SI eklem MRG bulgularının yorumlanmasında gözlemciler arasında farklılıklar olabilir. Amacımız, gözlemciler arasındaki uyumu araştırmaktır. Yöntem ve Gereçler Çalışma, sakroiliak MRG bulgularına dayanarak aktif veya kronik sakroileit teşhisi konulan ve/veya MRG sonuçları birincil hekim tarafından sakroileiti gösterir nitelikte bulunan 1150 hastanın MRG sonuçlarını içeriyordu. 1150 MRG uzman bir radyolog tarafından yeniden değerlendirildi. Bulgular Bu çalışma kapsamında incelenen toplam 1150 hastadan; uzman radyologun değerlendirmeleri ile dış kaynaklı radyolog değerlendirmeleri arasında istatistiksel olarak anlamlı bir farklılık ortaya çıktı. Sonuç Spondiloartropatilerin teşhisi bazı nedenlerle gecikebilir. Eğer hastanın klinik durumu ve MRG raporu tam uyum göstermiyorsa, hastanın takipten çıkarılmaması gerekmektedir.

Interobserver Agreement in Magnetic Resonance Imaging of Active Sacroiliitis

Abstract

Introduction Axial spondyloarthritis has characteristic clinical features such as enthesitis, sacroiliitis and spondylitis, and extra-articular manifestations. Sacroiliitis (SI) occurs as a result of inflammation of the sacroiliac joint. Magnetic resonance imaging (MRI) of sacroiliac (SI) joints is used to detect early sacroiliitis. Sometimes, there can be variations in the interpretation of MRI findings of the SI joint among observers. Our aim was to investigate the inter-observer agreement among the observers. Materials and methods The study included the MRI results of 1150 patients who were diagnosed with active or chronic sacroiliitis based on the findings from sacroiliac MRIs, or whose MRI was deemed indicative of sacroiliitis by the rheumatologist. 1150 MRIs were re-evaluated by a different and expert radiologist. Results Out of the total 1150 patients investigated within the scope of this study. A statistically significant disparity emerged between the assessments provided by the expert radiologists and those obtained from outsourced radiologist evaluations. Conclusion The diagnosis of spondyloarthropathy may be delayed for some reasons. If the patient's clinic and MRI report are not consistent, the patient should not be removed from follow-up.
