The hips of 8 young volunteers were investigated with high resolution MRI. The purpose of this study was to establish an imaging protocol to visualize hyaline cartilage, synovial fluid, and subchondral bone with optimized contrast. Spin Echo (SE) and Gradient Echo (GE) sequences were compared. FISP with a flip angle of 70 degrees was superior to the other techniques. The same sequences were applied on 45 volunteers aged 65-93 years. Early signs of degenerative arthritis of the hip were demonstrated as thinning, variable signal intensities within the cartilage layer, and cartilage loss. MRI of the hip may be a useful tool for the detection of early degenerative cartilage damage which cannot be documented with conventional x-rays.
对8名年轻志愿者的髋部进行了高分辨率磁共振成像（MRI）检查。本研究的目的是建立一种成像方案，以优化对比度来显示透明软骨、滑液和软骨下骨。对自旋回波（SE）序列和梯度回波（GE）序列进行了比较。翻转角为70度的快速成像稳态进动序列（FISP）优于其他技术。对45名年龄在65至93岁的志愿者应用了相同的序列。髋部退行性关节炎的早期迹象表现为软骨层变薄、软骨层内信号强度变化以及软骨缺失。髋部MRI可能是检测早期退行性软骨损伤的有用工具，而传统X线片无法记录这种损伤。
