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 uses a real-time form of x-ray called fluoroscopy and an injection of contrast material to evaluate the spinal cord, nerve roots and spinal lining (meninges). It is particularly useful for assessing the spine following surgery and for assessing disc abnormalities in patients who cannot undergo MRI. 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.
