Computed tomography (CT) easily and accurately demonstrates both the normal and abnormal adrenal gland. The normal adrenal gland can be seen in almost 95% of patients. With this technique, 29 of 29 proved adrenal masses were demonstrated; one case of bilateral adrenal hyperplasia could not be recognized, another showed equivocal enlargement. CT is an excellent screening and often definitive radiologic test for evaluating the adrenal gland.
