MRI and CT findings were reviewed from 11 patients with musculoskeletal haemangiomas. With MRI, morphological characteristics and extent of haemangiomas were optimally demonstrated on T2-weighted spin echo scans. High-resolution contrast-enhanced CT provided equivalent information regarding lesional characteristics and extent for small, localized haemangiomas. In CT evaluation of the extent of large haemangiomas, the radiation dose, transaxial scan plane, amount of intravenous contrast medium required and the necessity for correct timing of post-contrast scans became limiting factors. For such lesions, particularly those extending into the trunk, MRI supplemented by a plain radiograph is the optimum method of evaluation.
对11例肌肉骨骼血管瘤患者的MRI和CT检查结果进行了回顾。通过MRI，在T2加权自旋回波扫描上能最佳地显示血管瘤的形态特征和范围。高分辨率增强CT对于小的局限性血管瘤的病变特征和范围能提供等效信息。在CT评估大血管瘤的范围时，辐射剂量、横断面扫描平面、所需静脉造影剂的量以及造影剂后扫描正确时间的必要性成为限制因素。对于此类病变，尤其是那些延伸至躯干的病变，辅以平片的MRI是最佳评估方法。
