Abstract

Objectives: Outcome measures in Rheumatology (OMERACT) Juvenile Idiopathic Arthritis MRI Score in the sacroiliac joint (JAMRIS-SIJ) have been developed by the Rheumatoid Arthritis Study Group for the need for a standardized evaluation of SIJ in children. This study aims to evaluate the interrater reliability (IRR) of JAMRIS SIJ.

Methods: Patients younger than 18 years with a diagnosis of enthesitis-related arthritis and who had a sacroiliac MRI scan between October 2014 and December 2023 were enrolled in the study. Demographic data of the patients were recorded from clinical charts. Five raters examined the MRI scans and JAMRIS SIJ scores were recorded. IRR was assessed with intraclass correlation coefficient (ICC).

Results: The study comprised 40 MRI examinations of 31 patients. Fifteen of 31 patients were female. The median age at referral for scanning was 14.4 years. The ICC was 0.870 (0.780-0.935) (P < .001) and 0.654(0.473-0.791) (P < .001); for the inflammation and structural damage domains, respectively. Bone marrow edema had the highest IRR (ICC = 0.910 [0.863-0.946]; P < .001) from all components evaluated in JAMRIS-SIJ, and fat lesion had the highest IRR (ICC = 0.764 [0.648-0.855]; P < .001) from structural damage components.

Conclusions: Our results indicate that JAMRIS SIJ is reliable in evaluating most inflammation and structural damage components. JAMRIS SIJ may be used as a quantitative guide for the therapeutic management of patients with JIA.

Advances in knowledge: JAMRIS-SIJ is a reliable tool for evaluating inflammatory and structural damage components of sacroiliitis.

风湿病预后指标可靠性评估（OMERACT）青少年特发性关节炎骶髂关节磁共振成像评分系统（JAMRIS SIJ）。

目的：类风湿关节炎研究小组开发了儿童特发性关节炎骶髂关节MRI评分（JAMRIS-SIJ），以满足对儿童SIJ的标准化评估需求。本研究旨在评估JAMRIS SIJ的互译信度。方法：在2014年10月至2023年12月期间接受骶髂MRI扫描的年龄小于18岁、诊断为麻醉相关关节炎的患者被纳入研究。从临床图表中记录患者的人口统计资料。五名评分者检查了MRI扫描结果，并记录了JAMRIS SIJ评分。用组内相关系数评价组间信度。结果：本研究共对31例患者进行了40次MRI检查。31例患者中15例为女性。转诊时的中位年龄为14.4岁。类内相关系数为0.870 (0.780-0.935)(p)。结论：JAMRIS SIJ在评估大多数炎症和结构损伤成分方面是可靠的。JAMRIS SIJ可作为JIA患者治疗管理的定量指南。知识进展：小儿特发性关节炎骶髂关节磁共振成像评分系统是评估骶髂炎炎症和结构损伤成分的可靠工具。

期刊介绍： BJR is the international research journal of the British Institute of Radiology and is the oldest scientific journal in the field of radiology and related sciences. Dating back to 1896, BJR’s history is radiology’s history, and the journal has featured some landmark papers such as the first description of Computed Tomography "Computerized transverse axial tomography" by Godfrey Hounsfield in 1973. A valuable historical resource, the complete BJR archive has been digitized from 1896.
