在65项磁共振（MR）研究中，确定了6个颈椎节段上椎间孔（IVF）的方位，以解释45度标准X线斜位片上明显的大小和形状变化。磁共振成像数据分析表明，在整个颈椎中，颈椎IVF的方向发生了实质性变化，标准X线摄影的55度前后位（AP）斜位可能会导致下颈椎IVF更好的可视化。两具尸体标本的影像学和解剖学研究证实了这些结果。在23例患者的前瞻性临床研究中，通过测量所有宫颈IVF的最大横径来比较45度和55度AP斜位视图。在所有下颈椎节段，55度AP斜位投照的IVF尺寸显著增加。颈椎55 °前后斜位片是评价下颈椎孔的最佳选择，在分析所有颈椎孔时，可以作为45 °斜位片的常规替代。
The orientation of the intervertebral foramina (IVF) at six cervical levels on transaxial images in 65 magnetic resonance (MR) studies was determined to explain variations in size and shape evident on the 45-degrees standard radiographic oblique view. Analysis of MR imaging data showed that substantial variations in the orientation of the cervical IVFs occurred throughout the cervical spine and that a 55-degrees anteroposterior (AP) oblique view with standard radiography probably would lead to better visualization of the lower cervical IVFs. These results were confirmed with a radiographic and anatomic study of two cadaveric specimens. In a prospective clinical study of 23 patients, 45-degrees and 55-degrees AP oblique views were compared by measuring the maximal transverse diameter of all the cervical IVFs. IVF size was substantially increased on the 55-degrees AP oblique projection at all lower cervical levels. The 55-degrees AP oblique view of the cervical spine is optimal for evaluating the lower cervical foramina and can be a routine alternative to the 45-degrees oblique view in the analysis of all cervical foramina.
