Computed tomography and gray scale ultrasonography of the adrenal gland: a comparative study.

A prospective analysis of computed tomography and gray scale ultrasonography of the adrenal gland in 34 patients is presented. The diagnostic probabilities were similar for both modalities. Pitfalls common to both procedures and specific to one technique are demonstrated. The relative role of computed tomography and gray scale ultrasonography in evaluation of adrenal abnormalities is discussed in light of specific pathologies and other noninvasive imaging procedures.
