Pain affecting the foot and ankle is a common complaint frequently attributable to inflammatory joint diseases. Although conventional radiography is regarded as the initial step in the diagnostic investigation, MR imaging may contribute to further evaluation of these patients due to the direct visualization of the inflammatory soft tissue formed in the disease and its effects on bone, cartilage and para-articular structures. The high spatial resolution of MR imaging combined with tissue characterization often allows initial detection of inflammatory joint abnormalities at a stage that precedes radiographic evaluation. The typical MR appearance of certain inflammatory joint disorders may be helpful in narrowing the wide differential diagnosis. Furthermore, MR imaging can be used for an exact assessment of the extent of the disorder as well as its complications. Accurate diagnostic information can guide the clinician in further diagnostic tests and implementation of proper therapeutic treatment.
影响足部和踝关节的疼痛是一种常见的主诉，常归因于炎性关节疾病。尽管传统放射摄影被视为诊断性检查的第一步，但由于能直接观察到疾病中形成的炎性软组织及其对骨骼、软骨和关节周围结构的影响，磁共振成像（MR成像）可能有助于对这些患者进行进一步评估。MR成像的高空间分辨率与组织特征相结合，常常能在放射学评估之前的阶段初步检测出炎性关节异常。某些炎性关节疾病的典型MR表现可能有助于缩小广泛的鉴别诊断范围。此外，MR成像可用于准确评估疾病的范围及其并发症。准确的诊断信息可指导临床医生进行进一步的诊断测试并实施适当的治疗。
