| 中文摘要: |
| 目的 明确正常骨骺和生长板软骨在MR增强扫描成像中的表现。方法 分析10头乳猪的40个股骨近端和远端骨骺MR表现及不同解剖区域的增强率,并将MR表现与相应组织学发现进行对照。结果 Gd增强MR成像能够区别骨骺软骨和生长板软骨,显示骨骺内的血管槽。生长板软骨的增强率明显大于骨骺软骨(P＜0.005)。结论 生长板、骨骺软骨和骨骺软骨内血管槽具有不同的增强MRI表现。 |

| Objective To define the appearance of normal epiphyseal and physeal cartilage on Gadolinium-enhanced MRI. Methods MR appearance of 40 proximal and distal femoral ends in 10 healthy piglets using Gd-enhanced MR imaging were studied. Results Gd-enhanced MRI enabled to make differentiation between physeal and epiphyseal cartilage and reveal epiphyseal vascular canals. Enhanced ratios in physeal cartilage were bigger than those in epiphyseal cartilage P<0.005. Conclusion Gd-enhanced MR imaging enables to show difference in enhancement between physis and epiphyseal cartilage, and reveal epiphyseal vascular canals. |
