Comment: - In cases of possible adenoma a noncontrast scan will be all that is needed if the HU value is 18 or less. For discussion of contrast's role in defining adenomas, please see syllabus in ctisus.com. When staging a suspected adrenal cancer, thin scans will include through the base of the heart to define IVC extension.
