Quantitative evaluation of axial vertebral rotation is essential for the determination of reference values in normal and pathological conditions and for understanding the mechanisms of the progression of spinal deformities. However, routine quantitative evaluation of axial vertebral rotation is difficult and error-prone due to the limitations of the observer, characteristics of the observed vertebral anatomy and specific imaging properties. The scope of this paper is to review the existing methods for quantitative evaluation of axial vertebral rotation from medical images along with all relevant publications, which may provide a valuable resource for studying the existing methods or developing new methods and evaluation strategies. The reviewed methods are divided into the methods for evaluation of axial vertebral rotation in 2D images and the methods for evaluation of axial vertebral rotation in 3D images. Key evaluation issues and future considerations, supported by the results of the overview, are also discussed.
对椎体轴向旋转进行定量评估，对于确定正常和病理状态下的参考值以及理解脊柱畸形进展机制至关重要。然而，由于观察者的局限性、所观察椎体解剖结构的特点以及特定的成像特性，椎体轴向旋转的常规定量评估既困难又容易出错。本文的范围是回顾从医学图像中定量评估椎体轴向旋转的现有方法以及所有相关出版物，这可能为研究现有方法或开发新方法及评估策略提供宝贵资源。所回顾的方法分为二维图像中椎体轴向旋转评估方法和三维图像中椎体轴向旋转评估方法。还讨论了关键评估问题及未来考量，并得到了综述结果的支持。
