State the importance of a regular review of radiographs of the cervical spine using specific diagnostic criteria. List the plain film radiographic views of the cervical spine taken for trauma series and for ambulatory imaging.
Myelography is an imaging examination that involves the introduction of a spinal needle into the spinal canal and the injection of contrast material in the space around the spinal cord and nerve roots (the subarachnoid space) using a real-time form of x-ray called fluoroscopy. Myelography is relatively safe and painless. 2  When a contrast material is injected into the subarachnoid space surrounding the nerve roots and spinal cord, it allows the radiologist to view outlines of the different areas of the spine that usually are not visible or distinguishable on x-rays.
