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 .0 0 5 )。结论 生长板。
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.
