There is no non-invasive in vivo method to assess intervertebral kinematics. Current kinematics models are based on in vitro bone reconstructions from computed tomography (CT)-scan imaging, fluoroscopy and MRIs, which are either expensive or deleterious for human tissues. Musculoskeletal ultrasound is an accessible, easy to use and cost-effective device that allows high-resolution, real-time imaging of bone structure.
The aim of this preliminary study was to compare the concordance of 3D bone modeling of lumbar vertebrae between CT-scan and ultrasound imaging and to study the intra and inter-reliability of distances measured on 3D ultrasound bone models.
CT-scan, ultrasound, and in situ data of five lumbar vertebrae from the same human specimen were used. All vertebrae were scanned by tomography and a new musculoskeletal ultrasound procedure. Then, 3D bone modeling was created from both CT-scan and ultrasound image data set. Distances between anatomical bones landmarks were measured on the 3D models and compared to in situ measurements.
目前尚无非侵入性的体内方法来评估脊柱运动学。目前的运动学模型基于从 CT 扫描成像、透视和 MRI 重建的体外骨骼，这些方法要么昂贵，要么对人体组织有害。肌肉骨骼超声是一种易于使用且具有成本效益的设备，可实现骨骼结构的高分辨率实时成像。
本初步研究的目的是比较 CT 扫描和超声成像在腰椎三维骨骼建模中的一致性，并研究三维超声骨骼模型上测量距离的内部和外部可靠性。
使用同一人体标本的五个腰椎的 CT 扫描、超声和原位数据。所有椎体均通过断层扫描和新的肌肉骨骼超声程序进行扫描。然后，从 CT 扫描和超声图像数据集创建三维骨骼模型。在三维模型上测量解剖骨骼标志点之间的距离，并与原位测量值进行比较。
