The intervertebral foramen (also called neural foramen, and often abbreviated as IV foramen or IVF) is a foramen between two spinal vertebrae. Cervical, thoracic, and lumbar vertebrae all have intervertebral foramina. The foramina, or openings, are present between every pair of vertebrae in these areas. A number of structures pass through the foramen. These are the root of each spinal nerve, the spinal artery of the segmental artery, communicating veins between the internal and external plexuses, recurrent meningeal (sinu-vertebral) nerves, and transforaminal ligaments. When the spinal vertebrae are articulated with each other, the bodies form a strong pillar that supports the head and trunk, and the vertebral foramen constitutes a canal for the protection of the medulla spinalis (spinal cord). The size of the foramina is variable due to placement, pathology, spinal loading, and posture. Foramina can be occluded by arthritic degenerative changes and space-occupying lesions like tumors, metastases, and spinal disc herniations. Specifically, the intervertebral foramen is bordered by the superior notch of the adjacent vertebra, the inferior notch of the vertebra, the intervertebral joint and the intervertebral disc.

- Technique: - Trauma Oblique: - Technique Trauma Oblique: Which cervical oblique will show the left intervertebral foramen IVF )?The posterior cervical oblique projections demonstrate the intervertebral foramina and pedicles on the side closest to the image receptor.
Which projection is safer for the patient to demonstrate the left intervertebral foramina?How is the patient positioned to demonstrate the left intervertebral foramina of the cervical vertebrae? The left intervertebral foramina may be demonstrated by a 45-degree LAO or RPO position.
What does oblique C spine show?The oblique view shows the intervertebral foramina formed by the inferior notch of the pedicle of the vertebrae above and the superior notch of the pedicle of the vertebrae below. Oblique cervical spine views can be performed erect or supine and AP or PA.
Which projection opens the intervertebral disk spaces of the cervical spine?The anteroposterior (AP) cervical spine projection is part of the cervical spine series.
