To describe and evaluate the current knowledge of MRI characteristics of osteitis condensans ilii (OCI) in the diagnostics and differentiation of OCI from other conditions.
The databases PubMed, EMBASE, Scopus, and Web of Science were searched from their inception to March 2024 using the search terms "Magnetic Resonance Imaging" (MESH term in PubMed) and "osteitis condensans ilii" and limited to English language. Two reviewers independently screened titles, abstracts, and full-text eligibility and assessed the risk of bias according to Quality Assessment of Diagnostic Accuracy Studies, QUADAS-2.
The search identified 53 records. Case reports, letters/notes, and conference abstracts were excluded, resulting in 24 reports assessed by full-text, 9 research articles, 14 reviews, and a book chapter. Five retrospective research studies were found eligible for the review. Detailed MRI features of OCI were only described in two studies of patients with pain where they encompassed manifest subchondral iliac sclerosis often accompanied by bone marrow edema (BME) located peripheral to the sclerosis and displaying a continuous distribution and frequently accompanied by sacral BME. Erosions were rare and ankylosis did not occur. Fat deposition in the bone marrow was frequent and similar to BME often located to anterior strain-related joint areas. The QUADAS-2 assessments revealed risks of bias in all studies analyzed, especially regarding general applicability of the MRI features.
There is a lack of valid data describing characteristic MRI features in general groups of OCI patients with and without pain.
描述并评估致密性骨炎（OCI）的MRI特征在OCI诊断及与其他病症鉴别诊断方面的当前认知。
使用检索词“磁共振成像”（PubMed中的医学主题词）和“致密性骨炎”，从数据库PubMed、EMBASE、Scopus和Web of Science建库起至2024年3月进行检索，并限定语言为英语。两名审阅者独立筛选标题、摘要和全文的合格性，并根据诊断准确性研究的质量评估（QUADAS - 2）评估偏倚风险。
检索共识别出53条记录。排除病例报告、信函/笔记和会议摘要后，有24篇报告进行了全文评估，包括9篇研究文章、14篇综述和1章书籍内容。发现有5项回顾性研究符合综述要求。仅在两项针对有疼痛症状患者的研究中描述了OCI的详细MRI特征，这些特征包括明显的髂骨软骨下硬化，常伴有位于硬化周边的骨髓水肿（BME），呈连续分布，且常伴有骶骨BME。侵蚀罕见，未发生强直。骨髓内脂肪沉积常见，与BME相似，常位于前侧与劳损相关的关节区域。QUADAS - 2评估显示，所有分析的研究均存在偏倚风险，尤其是关于MRI特征的一般适用性方面。
缺乏关于有疼痛和无疼痛的OCI患者总体人群特征性MRI特征的有效数据。
