Align the midsagittal plane of the patient's body to the midline of the table or IR. To achieve the best angle, the central ray should be directed at an angle that parallels the plane of the mandible and then directed to just below the hyoid bone. Positioning for an AP projection of the cervical spine The patient is placed in the supine or upright position with their back against the cassette holder the shoulders should lie in the same horizontal plane to prevent rotation. An excessive or insufficient angle can distort these disc spaces. To project the intervertebral disc spaces open, the central ray should be directed perpendicular to the long axis of the vertebral column 3, 4. This angle can and will vary between 5-20° depending on the position of the head. For this reason, a cephalic angle is required to project through the long axis of the vertebral column. It is seldom conducted in isolation, often part one of the two part clavicle series. It can be requested as part of a concentrated radiograph to assess for metastasis or multiple myeloma. anteroposterior projection of the cervical spine demonstrating the vertebral bodies and intervertebral spaces. The AP clavicle is often indicated in patients with suspected clavicular injuries following trauma such as falling onto ones side. Correcting tube angle errors and head tilt errorsĪ lordotic curvature exists in the cervical spine. Note: in the absence of CT 5 views of the C-spine should be performed: AP, lateral, obliques and odontoid 5. The spinous process will rotate toward the pedicle of the side farther from the image receptor 3. The spinous process should be midline of the vertebral body, equidistant from both pedicles 3. Any deviation from the midline indicates rotation is present. Some pathologies of the entire cervical vertebrae including dens and surrounding bony structures of the C1 ring. A support may be placed under the elevated parts of the body ( ). The patient should be asked to hold the breath during exposure. Entire cervical spine with the mandible blurred. The lumbar spine is approximately 2 inches medial to the elevated anterior superior iliac spine in the oblique position. Rotation can be detected by looking at the spinous processes in relation to the pedicles. Cervical - AP ('Wagging Jaw') Area Covered. ![]()
