Note:—Appropriateness criteria scale from 1 to 9; 1, least appropriate; 9, most appropriate.
* CT myelography, cervical and/or thoracic spine = rating of 6, X-ray, myelography, cervical and/or thoracic spine = rating of 5 and usually performed with CT.
^a One or more anatomically contiguous studies may be appropriate depending on clinical circumstances.
^b May be appropriate if malignancy suspected.
^c May be useful for staging and characterizing local lesion.
^d Best imaging tool to distinguish between tumor recurrence and radiation plexopathy.
