Radiography is the mainstay for initial evaluation of paediatric foot and ankle pathology. MRI is the preferred exam for further characterisation of the majority of these conditions. The modality features high sensitivity and specificity for this purpose with few exceptions. Findings on MRI will often dictate patient referral and further management, and are frequently required for surgical planning. This article will provide an overview of a variety of pathologies that afflict the foot and ankle in children. These include tarsal coalition, osteochondral lesions, osteonecrosis, osteochondroses, stress fractures, osteomyelitis, inflammatory arthritis, neoplasms of bone and soft tissue, and foreign bodies. Their respective imaging manifestations on MRI are the focus of the paper. Technical parameters and marrow signal variation are also discussed.
放射摄影是儿科足踝病理学初步评估的主要方法。对于大多数此类疾病，MRI 是进一步特征描述的首选检查方法。这种方式具有很高的敏感性和特异性，除了少数例外情况。MRI 的结果通常决定了患者的转诊和进一步的治疗，并经常需要用于手术计划。本文将概述影响儿童足踝的各种病变。这些病变包括跗骨联合、骨软骨病变、骨坏死、骨软骨病、应力性骨折、骨髓炎、炎症性关节炎、骨和软组织肿瘤以及异物。本文重点介绍它们在 MRI 上的各自影像学表现。还讨论了技术参数和骨髓信号变化。
