The capability of magnetic resonance imaging (MRI) to visualize early degenerative arthritis of the hip was investigated. The study was performed on 8 healthy students and 45 elderly volunteers. Images were obtained by using an electronically variable Helmholtz coil (switched-array coil, SAC). In order to diagnose degenerative lesions of the joint cartilage, FISP sequences with a flip angle of 70 degrees were found preferable to compared sequences. MRI-detectable signs of degenerative arthritis of the hip were narrowed joint space due to partially thinned cartilage layers, focal areas of either increased or decreased signal intensity in the hyaline cartilage, complete loss of cartilage, and signal variation in the bone marrow. MRI of the hip may be appropriate to detect early degenerative changes in the hips of young high-risk patients to facilitate therapy planning.
研究了磁共振成像（MRI）可视化早期髋关节退行性关节炎的能力。该研究对8名健康学生和45名老年志愿者进行。使用电子可变亥姆霍兹线圈（开关阵列线圈，SAC）获取图像。为了诊断关节软骨的退行性病变，发现翻转角为70度的快速成像稳态自由进动（FISP）序列比对照序列更可取。髋关节退行性关节炎的MRI可检测征象包括由于软骨层部分变薄导致的关节间隙变窄、透明软骨中信号强度增加或降低的局灶性区域、软骨完全缺失以及骨髓信号变化。髋关节MRI可能适用于检测年轻高危患者髋关节的早期退行性变化，以利于治疗规划。
