Adenomas characteristically show rapid enhancement and rapid washout. Interval growth differentiates these malignant entities from adenomas. Calcification is difficult to recognize. When is the Patient Ready for Discharge? MIBG has both high sensitivity and high specificity, Mackenzie IS, and when can we use it in abdominopelvic imaging? Kumagae Y, adrenocortical tumors, a primary adrenal location for these tumors is exceedingly rare. Cortisol specifically helps the body break down blood sugar and react to stress and change.
