Diagnostic imaging is crucial to the diagnosis and monitoring of spondyloarthropathies. Magnetic resonance imaging is the most relevant tool for the early detection of sacroiliitis, allowing the institution of therapeutic strategies to impede the progression of the disease. This study illustrates the major criteria for a magnetic resonance imaging-based diagnosis of spondyloarthropathy. The cases selected here present images obtained from the medical records of patients diagnosed with sacroiliitis over a two-year period at our facility, depicting the active and chronic, irreversible forms of the disease. Although computed tomography and conventional radiography can also identify structural changes, such as subchondral sclerosis, erosions, fat deposits, and ankylosis, only magnetic resonance imaging can reveal active inflammatory lesions, such as bone edema, osteitis, synovitis, enthesitis, and capsulitis.
诊断成像对于脊柱关节病的诊断和监测至关重要。磁共振成像（MRI）是早期检测骶髂关节炎最有效的工具，有助于制定治疗策略以阻止疾病进展。本研究阐述了基于磁共振成像诊断脊柱关节病的主要标准。这里选取的病例呈现了从我们机构两年内诊断为骶髂关节炎的患者病历中获取的图像，描绘了该疾病的活动期和慢性不可逆形式。虽然计算机断层扫描（CT）和传统X线摄影也能识别结构变化，如软骨下硬化、侵蚀、脂肪沉积和关节强直，但只有磁共振成像能显示活跃的炎性病变，如骨髓水肿、骨炎、滑膜炎、附着点炎和囊炎。
