Figure 4From: Distinguishing benign from malignant adrenal masses(a) Mean density measurements of lipid-rich, lipid-poor adenomas and non-adenomas on unenhanced, enhanced and delayed CT images showing that differentiation between lipid-poor adenomas and non-adenomas is not possible. (b) Mean percentage and relative percentage washout of lipid-rich, lipid-poor adenomas and non-adenomas on unenhanced, enhanced and delayed CT images showing that lipid-poor adenomas can be distinguished from non-adenomas.Back to article page
