Figure 2b.  (a) Axial T1-weighted fast spin-echo (repetition time msec/echo time msec = 749/12) MR image of the abdomen obtained at the level of the adrenal glands shows a heterogeneously hypointense left adrenal mass. Note the area of intermediate signal intensity (from subacute blood) within the mass (arrowhead). (b) Axial T2-weighted fast spin-echo (3,150/102) MR image shows the left adrenal mass (arrow) as slightly heterogeneous and nearly isointense relative to the liver.
