Abstract：
OBJECTIVE: To reveal the differences by comparing the magnetic resonance imaging (MRI) findings of patients with clinically symptomatic sacroiliitis with those undergoing sacroiliac imaging for other reasons using the Canadian Spondyloarthritis Research Consortium-Sacroiliac Inflammatory Scoring System (SPARCC-SIS).
METHODS: In this retrospective single-center study, sacroiliac MRIs performed between 2017 and 2023 were evaluated from the database. The SPARCC-SIS scoring system is used to evaluate and grade the inflammation of the sacroiliac joints. Mild inflammation is indicated by a score below 24, moderate by a score of 24-48, and severe by a score above 49. Additionally, structural defects of the sacroiliac joint, such as erosion, sclerosis, and ankylosis, were observed. After MRI evaluation, clinically symptomatic (group 1) and non-symptomatic (group 2) patients were divided into two groups. The clinical and laboratory findings of the patients and MRI findings were compared. The patient\'s age, gender, clinical information from hospital records, acute phase reactants (APRs), and the presence of the Human Leukocyte Antigen (HLA-B27) gene (if applicable) were thoroughly recorded.
RESULTS: One hundred thirty-six children who performed sacroiliac MRI for any indication were included in the study. The APRs positivity, presence of HLA-B27, and SPARCC scoring system were significantly higher in 24 patients with clinical sacroiliitis (group 1) than in 112 patients without sacroiliitis (group 2). In our study, the most common MRI findings in children were bone marrow edema, capsulitis, synovitis, and erosion, while chronic structural changes such as sclerosis and ankylosing were rare.
CONCLUSIONS: In this study, the SPARCC scoring method, which shows the severity of sacroiliac joint inflammation, correlates with the clinical diagnosis of sacroiliitis. In cases with suspected sacroiliitis, except for extraordinary reasons, it can be evaluated with MRI without contrast material and can be graded to guide the clinician in treatment and approach.

摘要：
目的：通过比较临床症状骶髂关节炎患者与其他原因使用加拿大脊柱关节炎研究联盟-骶髂炎症评分系统（SPARCC-SIS）进行骶髂关节成像的磁共振成像（MRI）结果，揭示差异。
方法：在这项回顾性单中心研究中，从数据库中评估了2017年至2023年间进行的骶髂MRI.SPARCC-SIS评分系统用于评估和分级骶髂关节的炎症。轻度炎症由低于24的分数表示,中等的分数为24-48,严重的分数为高于49。此外,骶髂关节结构缺陷,比如侵蚀，硬化症,和强直,被观察到。MRI评估后,有临床症状(第1组)和无症状(第2组)的患者被分为两组.比较患者的临床和实验室检查结果以及MRI检查结果。病人的年龄,性别,来自医院记录的临床信息，急性期反应物（APRs），彻底记录人类白细胞抗原(HLA-B27)基因(如果适用)的存在。
结果：研究中纳入了136名接受骶髂关节MRI检查的儿童。APRs积极，24例临床骶髂关节炎患者(第1组)的HLA-B27和SPARCC评分系统的存在显著高于112例无骶髂关节炎患者(第2组).在我们的研究中,儿童最常见的MRI表现是骨髓水肿，囊炎,滑膜炎,和侵蚀，而硬化和强直性等慢性结构改变很少见。
结论：在这项研究中，SPARCC评分法，显示骶髂关节炎症的严重程度，与骶髂关节炎的临床诊断有关。在怀疑骶髂关节炎的病例中，除了特别的原因,它可以在没有造影剂的情况下使用MRI进行评估，并且可以进行分级以指导临床医生的治疗和入路。
