Magnetic resonance imaging (MRI) has allowed a comprehensive evaluation of articular disease, increasing the detection of early cartilage involvement, bone erosions, and edema in soft tissue and bone marrow compared to other imaging techniques. In the era of functional imaging, new advanced MRI sequences are being successfully applied for articular evaluation in cases of inflammatory, infectious, and degenerative arthropathies. Diffusion weighted imaging, new fat suppression techniques such as DIXON, dynamic contrast enhanced-MRI, and specific T2 mapping cartilage sequences allow a better understanding of the physiopathological processes that underlie these different arthropathies. They provide valuable quantitative information that aids in their differentiation and can be used as potential biomarkers of articular disease course and treatment response.
与其他成像技术相比,磁共振成像(MRI)能够对关节疾病进行全面评估,提高了对早期软骨受累、骨质侵蚀以及软组织和骨髓水肿的检测能力。在功能成像时代,新的先进MRI序列已成功应用于炎症性、感染性和退行性关节病的关节评估。扩散加权成像、诸如DIXON等新的脂肪抑制技术、动态对比增强MRI以及特定的T2映射软骨序列,有助于更好地理解这些不同关节病背后的生理病理过程。它们提供了有价值的定量信息,有助于鉴别诊断,并且可作为关节疾病病程和治疗反应的潜在生物标志物。
