磁共振对骨骺部位损伤的诊断及其临床应用

目的：探讨磁共振检查对骨骺部位损伤的诊断及临床应用。方法：选择10例骨骺部位损伤的病例。男6例，女4例，年龄7－15岁，平均年龄10．8岁。所有病例先行X线检查，再应用Toshiba 1.5T和Marconi 1.5T MR扫描仪行磁共振检查。检查序列包括：SE T1WI、3D－FE、FSE T2WI。结果：10例12次伴有骨桥形成，其中中央型4例，1例伴有同侧肢体短缩；线样型4例，无肢体短缩或成角畸形，1例一年后随访骨桥消失；周围型2例，1例成角畸形，1例同时还伴有肢体短缩；4例线样型骨桥，X线检查为阴性。结论：与X线平片相比，MRI可以清晰显示骨骺部位软骨结构，MR已成为对骨骺部位检查的理想手段。

The clinical application of MR in the diagnosis of injury in the epiphyseal region

Objective:To probe the possibility of the clinical application of MRI in the diagnosis of injury of the epiphyseal region.Methods:Ten patients with a history of injury in the epiphyseal region were selected.The patients,including 6 boys and 4 girls,ranged in age from 7 to 15 years old with an average of 10.8 years old.For all of the patients,X-ray examinations were performed at first,then MR examination were accomplished with Toshiba and Marconi 1.5T MR scanner.MR sequences include:SE T 1WI,3D-FE,FSE T 2WI. Results:Twelve bony bridges were presented among 10 cases,four cases were central type and 1 case with angular deformity;Linear type bony bridge were seen in 4 cases without angular deformity or shortening.One case became normal after one year.Two were peripheral type.Besides angular deformity,one case was associated shortening.X-ray examination is negative of four linear types.Conclusion:Compared with X-ray examination,MR imaging could display cartilage structures clearly and be an optimal protocol for the examination of the epiphyseal region.
