Correlation and differences in cervical sagittal alignment parameters between cervical radiographs and magnetic resonance images

Correlation and differences in cervical sagittal alignment parameters between cervical... Purpose Although cervical alignment is better assessed using standing radiography than supine magnetic resonance imaging (MRI), few studies have investigated this.

Inter- and intra-group analyses were conducted to identify any difference between standing radiography and supine MRI. Statistical differences between the cervical parameters were compared.

Abstract

Purpose Although cervical alignment is better assessed using standing radiography than supine magnetic resonance imaging (MRI), few studies have investigated this. This study aimed to investigate the die ff rence in alignment between standing radio - graphs and supine MRI images, and assess whether neck position affects the cervical parameters and neurological changes. Methods We analyzed 53 patients, measuring the O–C2 angle, C2–7 angle (the distinction between the lordotic and kyphotic groups), T1 slope, neck tilt, thoracic inlet angle, and the C2–7 sagittal vertical axis. Inter- and intra-group analyses were conducted to identify any difference between standing radiography and supine MRI. Statistical differences between the cervical parameters were compared. Results Strong correlations were noted between the equivalent parameters in the radiographs and MRI images, whereas no significant difference was observed in C2–7 angle in the kyphotic group between the radiographs and MRI images, or for neck tilt between the radiographs and MRI images. However, in the lordotic group, the C2–7 angle was significantly differ - ent between the two types of images and larger in the radiographs than in the MRI images (C2–7 angle in the radiographs: C2–7 angle in the MRI images: 4.49°, p < 0.001).
