Technological advancements in the diagnostic radiology recently permitted reviewing the normal anatomy through multidetector computed tomography (MDCT) imagination. The aim of this paper is retrospectively investigation of the clival foramen and canal through MDCT.
One hundred eighty-six MDCT scans were reviewed. First, images were taken at axial plane, and then coronal and sagittal reconstructions of raw data were performed. Later investigations were carried out on these three-dimensional images (3-D imaging). The images were evaluated as clival foramen "present" or "absent."
In our 186 patients, evaluation of MDCT showed that clival foramen was absent in 66.7% (n = 124) of patients. Only 33.3% (n = 62) of patients had a clival foramen. In 3-D images, clival canal and clival foramen were shown more clearly compared with the MDCT.
Knowledge of the clival canal might be useful in patients of questionable clival fracture or during neurosurgical operations in this region. During life the canal contained a vein connecting the basilar plexus with the venous plexus of the vertebral canal, and inferior petrosal sinuses. Before the surgical interventions in the clival region, the presence of the clival canal and foramen should also be known due to its vascular contents. By multidetector computed tomography and 3-D images, clival canal and foramen may be viewed preoperatively.
诊断放射学的技术进步使得通过多排螺旋计算机断层扫描（MDCT）成像来观察正常解剖结构成为可能。本文旨在通过MDCT对斜坡孔和管进行回顾性研究。
回顾了186例MDCT扫描。首先在轴位平面采集图像，然后对原始数据进行冠状位和矢状位重建。随后对这些三维图像（3D成像）进行研究。图像被评估为斜坡孔“存在”或“不存在”。
在我们的186例患者中，MDCT评估显示66.7%（n = 124）的患者没有斜坡孔。只有33.3%（n = 62）的患者有斜坡孔。在3D图像中，与MDCT相比，斜坡管和斜坡孔显示得更清晰。
了解斜坡管可能对斜坡骨折存疑的患者或该区域的神经外科手术有用。在生命过程中，该管内有一条连接基底丛和椎管静脉丛的静脉以及岩下窦。在斜坡区域进行手术干预之前，由于其血管内容物，也应该了解斜坡管和孔的存在情况。通过多排螺旋计算机断层扫描和3D图像，可以在术前观察到斜坡管和孔。
