Evaluate technical feasibility and potential applications of glenohumeral (GH) joint axial traction magnetic resonance imaging (MRI) in healthy volunteers.
Eleven shoulders were imaged in neutral and with 4kg axial traction at 3T. Quantitative measurements were assessed.
Axial traction was well tolerated. There was statistically significant widening of the superior GH joint space (p=0.002) and acromial angle (p=0.017) with traction. Inter-rater agreement was high.
GH joint axial traction MRI is technically feasible and well tolerated in volunteers. Traction of the capsule, widening of the superior GH joint space and acromial angle were observed.
评估在健康志愿者中进行肩关节（GH）轴向牵引磁共振成像（MRI）的技术可行性和潜在应用。
对11个肩部在3T磁场下于中立位及施加4kg轴向牵引时进行成像。评估定量测量结果。
轴向牵引耐受性良好。牵引时，GH关节上方间隙（p = 0.002）和肩峰角（p = 0.017）有统计学意义的增宽。评分者间一致性高。
GH关节轴向牵引MRI在志愿者中技术上可行且耐受性良好。观察到关节囊牵引、GH关节上方间隙增宽和肩峰角增大。
