Cross-sectional imaging work-up of adrenal masses

Figure 4 Magnetic resonance imaging axial images of a right adrenal metastasis (arrows) from a primary non-small cell lung cancer. A: A non-contrast T1 image that demonstrates low T1 signal; B: A T2 image which demonstrates intermediate high T2 signal; C: A post-contrast image which demonstrates peripheral enhancement and a degree of internal signal wash-out.
