Abstract

This study was to describe the findings of osteonecrosis in patients with SLE at MR and scintigraphic imaging. Among 415 patients with SLE, 37 patients were diagnosed to have osteonecrosis. MR images and bone scintigraphs were analyzed for sites of involvement, signal intensity, bilaterality and multiplicity. MR imaging features of osteonecrosis in patients with SLE included isointense signal intensity relative to adjacent bone marrow, hypointense rim, marginal enhancement and unusual involvement of flat bones. Bilateral and multiple involvements were common.

摘要

本研究旨在描述系统性红斑狼疮（SLE）患者在磁共振成像（MR）和骨闪烁显像中的骨坏死表现。在415例SLE患者中，37例被诊断为骨坏死。对MR图像和骨闪烁显像进行分析，以确定受累部位、信号强度、双侧性和多发性。SLE患者骨坏死的MR成像特征包括相对于相邻骨髓的等信号强度、低信号边缘、边缘强化以及扁骨的异常受累。双侧和多发性受累很常见。
