【摘要】：目的探讨踝关节急、慢性损伤状态下踝关节韧带的MRI影像特征。方法对45例踝关节损伤患者行踝关节MR检查,评价踝关节韧带损伤的MRI特征表现,各韧带联合损伤特点,以及儿童踝关节韧带损伤特征。结果 45例患者中韧带损伤64条,急性损伤T2W及PD序列表现为受损韧带信号不均匀增高,韧带部分撕裂或完全断裂,界限不清,周围可见高信号积液影、软组织水肿及邻近骨髓水肿;慢性损伤主要表现为韧带的不规则增粗或变细,信号不均匀。外侧副韧带损伤37例(37/64,57.81%),以距腓前韧带损伤为主(24/45,53.33%)。8例(8/8,100%)患儿均为距腓前韧带损伤。结论踝关节韧带损伤MRI特征表现为T2WI不均匀增高伴韧带撕裂,以距腓前韧带损伤最为常见。
[Abstract]:Objective to investigate the MRI imaging features of ankle ligament under acute and chronic ankle injury. Methods 45 cases of ankle joint injury were examined by Mr examination. The MRI features of ankle ligament injury, the characteristics of joint injury of each ligament and the characteristics of ankle ligament injury in children were evaluated. Results among the 45 patients, 64 ligaments were injured, and acute injury T2W and PD sequences showed that the signal intensity of the injured ligaments was increased inhomogeneously, the ligaments were partially torn or completely broken, the boundary was not clear, and hyperintense effusion was observed around them. Soft tissue edema and adjacent bone marrow edema were mainly characterized by irregular thickening or thinning of ligaments and uneven signal intensity. There were 37 cases of lateral collateral ligament injury (37 / 64 / 57.81). The injury of the anterior talofibular ligament was mainly caused by 24 / 45 / 53.33.8 cases (8 / 8100). All of them suffered from the injury of the anterior talofibular ligament. Conclusion the MRI features of ankle ligament injury are uneven increase of T2WI with ligament tear, especially the injury of anterior talofibular ligament.
