Axial vertebral rotation (AVR) of 14 normal and 14 scoliotic vertebrae from magnetic resonance (MR) images was determined by three observers using four manual methods and a computerized method, which were based on the evaluation of vertebral symmetry in two dimensions (2D) and in three dimensions (3D). The method of Aaro and Dahlborn proved to be the manual method with the highest intra-observer (1.7 degrees SD) and inter-observer (1.2 degrees SD) reliabilities, and was also most in agreement with the computerized method (1.3 degrees SD, 1.0 degrees MAD). The computerized method yielded higher intra-observer (1.3 degrees SD) and inter-observer (1.4 degrees SD) reliabilities than the manual methods, indicating it to be an efficient alternative for repeatable and reliable AVR measurements.
采用四种手动方法和一种计算机化方法，通过三位观察者从磁共振（MR）图像中确定了 14 个正常和 14 个脊柱侧弯椎体的轴向椎体旋转（AVR），该方法基于二维（2D）和三维（3D）评估椎体对称性。Aaro 和 Dahlborn 方法被证明是手动方法，具有最高的观察者内（1.7 度 SD）和观察者间（1.2 度 SD）可靠性，并且与计算机化方法（1.3 度 SD，1.0 度 MAD）最一致。计算机化方法产生了更高的观察者内（1.3 度 SD）和观察者间（1.4 度 SD）可靠性，表明它是一种可重复和可靠的 AVR 测量的有效替代方法。
