The diagnosis of femoroacetabular impingement (FAI) syndrome requires that 3 prerequisites are met. Patient symptoms and physical examination must be combined with imaging to appropriately make the diagnosis. Imaging, including plain radiographs, magnetic resonance imaging (MRI), and computed tomography, should be interpreted in the context of a high prevalence of cam and pincer morphology, in addition to labral injury, in the general population. All images routinely obtained in current clinical practice are 2-dimensional representations of complex 3-dimensional processes. Although computerized modeling can dynamically manipulate femur and pelvis independently in fluoroscopy-, computed tomography-, and/or MRI-based collision detection models, the exact definition of "impingement" eludes the current literature. High-resolution, high magnet strength (minimum 3 Tesla), physiologic and/or biochemical dynamic MRI has the potential to image both soft and osseous tissues, interacting to best define hip impingement.
髋关节撞击综合征（FAI）的诊断需要满足 3 个前提条件。患者的症状和体格检查必须与影像学相结合，以便做出恰当的诊断。影像学检查包括 X 线平片、磁共振成像（MRI）和计算机断层扫描（CT），应结合高流行率的凸轮和钳子形态以及普通人群中的盂唇损伤进行解读。当前临床实践中常规获得的所有图像都是复杂三维过程的二维表现。虽然计算机建模可以在透视、CT 和/或 MRI 为基础的碰撞检测模型中独立动态操纵股骨和骨盆，但“撞击”的确切定义仍回避当前文献。高分辨率、高磁场强度（最低 3 特斯拉）、生理和/或生化动态 MRI 具有成像软组织结构和骨组织的潜力，可相互作用以最佳定义髋关节撞击。
