Over rotation of more than 45° would cause one pedicle to be foreshortened while the other pedicle aligns to the midline of the vertebral bodies 2. X-rays of the spine may be performed to evaluate any area of the spine (cervical, thoracic, lumbar, sacral, or coccygeal). If underrotated, the foramina will be narrowed and a sternoclavicular joint would be superimposed over the vertebral column 3. It appears as a dark line in the white bone. To demonstrate the intervertebral foramen of the c-spine open, it is necessary to achieve adequate rotation of the vertebral column, usually at 45°. using a larger source-to-image-distance will decrease the magnification of the image and improves acuity 2.make sure that any removable artefacts such as earrings, glasses, tongue piercings or metal dentures are removed to avoid obscuring the anatomy of interest.intervertebral foramina of the side positioned closer to the image receptor should be demonstrated open 4.MRI scans create better images of the bodys soft tissues, such as muscles, disks, nerves, and the spinal cord. It can also reveal degenerative changes in your cervical spine such as the loss of disk height or the presence of bone spurs. To ensure this ensure that the interpupillary line is perpendicular to the image receptor but also parallel to the floor An X-ray will show the alignment of the bones along your neck. patient’s head should be in a lateral position to prevent mandibular superimposition over the vertebral bodies of the cervical spine.all of the cervical spine should be included from C1-T1 Secondarily, scoliosis X-rays should include the entire spine, meaning from the neck to the pelvis this is necessary for getting the most accurate images of the spine.inferiorly include to at least T1 (EAM to vertebral prominence of C7 and/or T1).

anteriorly to include the soft tissue of the neck.laterally to include the entire cervical spine and its spinous processes.the thorax and cervical vertebral column at 45° to the image receptor.patient is standing erect with either their right or left anterior side closer to the image receptor.Moving the patient's head or neck, or removing a cervical collar could be detrimental. Note: Such views should not be performed on trauma patients without the strict instructions of a qualified clinician who has reviewed the lateral cervical spine image or CT of the cervical spine. This projection can be used to visualize pathology involving the adjacent soft tissue structures or cervical spine, especially stenosis of the intervertebral foramina.
