CT without contrast and CT myelography may be appropriate. National Library of Medicine While contrast dye usually leaves a patients system quickly, those with kidney function issues might have trouble processing the dye. In such cases medical practitioners can rule out nerve compression and must consider an alternative diagnosis.
