BIPLANAR IMAGING WITH TRIDIMENSIONAL CAPABILITIES: APPLICABILITY OF THIS NEW EXAMINATION TO SPINAL DEFORMITIES

ABSTRACT This study presents details about the applicability of the new image acquisition system, called the biplanar imaging system, with three-dimensional capabilities (EOS®) to the treatment of spinal deformities. This system allows radiographic acquisition of the entire body, with a great reduction in the dose of radiation absorbed by the patient and three-dimensional (3D) stereoradiographic image reconstruction of bone structures, including the spine. In the case of adolescent idiopathic scoliosis, the analysis of the spinal deformity with 3D reconstruction allows better understanding of the deformity and surgical planning. In the case of adult spinal deformity, full-body analysis allows an evaluation of the spinopelvic deformity, including loss of sagittal alignment, in addition to an evaluation of compensatory mechanisms recruited by the individual in an attempt to maintain the sagittal balance. Level of evidence III; Descriptive Review.

摘要 本研究详述了具备三维（3D）成像功能的新型图像采集系统——双平面成像系统（EOS®）在脊柱畸形治疗中的应用可行性。该系统可实现全身放射影像采集，大幅降低患者所受辐射剂量，并可对包括脊柱在内的骨骼结构开展三维立体放射影像重建。针对青少年特发性脊柱侧凸，借助三维重建对脊柱畸形进行分析，能够更清晰地认知畸形特征并辅助手术方案规划。针对成人脊柱畸形，全身成像分析可评估脊柱骨盆畸形（包括矢状面排列丢失），同时还可评估个体为维持矢状面平衡所启动的代偿机制。证据等级：III级；描述性综述。
