Real-time dynamic magnetic resonance imaging (MRI) in the musculoskeletal system touts the ability to perceive in vivo joint kinematics, which is particularly attractive for diagnosing dynamic pathologies such as joint instability or impingement syndromes.The clinical utility of dynamic MRI in the musculoskeletal system is wide ranging, from patellofemoral kinematics to imaging of the hip in femoroacetabular impingement and also dynamic spine imaging. Patellofemoral instability is an ideal diagnostic target, as knee flexion and extension are easily performed in an MRI scanner, and dynamic measurements have been correlated to clinical and static radiologic parameters of instability. Proving the clinical utility of this MRI technique requires rigorous technical standardization and definition of normal patellofemoral motion parameters. Validated imaging methods and rigorously defined normal range data are required to light the path forward, and the video format of dynamic MRI is also ideal for advancing patient-centered care, improving patient literacy on their condition, and offering a potential catalyst for shared decision-making between surgeons and their patients.
实时动态磁共振成像（MRI）在肌肉骨骼系统中具有感知关节运动力学的能力，这对于诊断关节不稳定或撞击综合征等动态疾病特别有吸引力。动态 MRI 在肌肉骨骼系统中的临床应用非常广泛，从髌股关节运动力学到髋关节撞击综合征的成像，以及动态脊柱成像。髌股关节不稳定是一个理想的诊断目标，因为膝关节的屈伸在 MRI 扫描仪中很容易进行，并且动态测量与不稳定的临床和静态放射学参数相关。要证明这种 MRI 技术的临床实用性，需要严格的技术标准化和正常髌股运动参数的定义。需要经过验证的成像方法和严格定义的正常范围数据来为前进指明道路，动态 MRI 的视频格式也非常适合推进以患者为中心的护理，提高患者对自身病情的了解程度，并为外科医生及其患者之间的共同决策提供潜在的催化剂。
