MR imaging can depict tumor volume and better delineate the extent of involvement than physical and CT examination. This can be useful for placement of radiation ports, especially when small boost fields are used.

Ten lumbar disk levels in nine patients were examined by computed tomography (CT) before and 6 weeks after chymopapain chemonucleolysis of herniated nucleus pulposus (HNP). Patient selection for chemonucleolysis was partly based on CT scans demonstrating morphologic HNP criteria favoring a successful treatment outcome. Posttreatment CT scans disclosed a measurable HNP size decrease of 1-3 mm at nine of 10 levels studied as well as an increase in HNP attenuation at many levels. CT findings correlated closely with objective clinical parameters used to assess treatment outcomes.
