Spica MRI is a fast and effective tool to assess morphology after closed reduction for developmental dysplasia of the hip (DDH) without the need for sedation. The multiplanar capabilities allow depiction of coronal and axial reduction of the hips. Due to MRI's inherent ability to delineate soft tissue structures, both intrinsic and extrinsic obstacles to failed reduction may be identified. Technical and interpretative challenges of spica MRI are discussed.
Spica MRI 是一种快速有效的工具，可在无需镇静的情况下评估发育性髋关节发育不良（DDH）闭合复位后的形态，具有多平面成像能力，可显示髋关节的冠状面和轴面复位。由于 MRI 具有固有区分软组织结构的能力，因此可以识别复位失败的内在和外在障碍。本文讨论了 Spica MRI 的技术和解读挑战。
