MRI kinematic analysis of T1 sagittal motion between cervical flexion and extension positions in 145 patients

摘要

PurposeAlthough the T1 vertebra is considered as an important factor of cervical balance, little is known about its motion between flexion and extension. The purpose of present study was to analyze the T1 sagittal motion using kinematic magnetic resonance imaging (kMRI), and to identify factors that relate to T1 sagittal motion.
