High specificity of chemical shift MR for benign adrenal lesions may aid differentiation; leaves open prospective validation before changing biopsy practice.
Do echo-planar, fast spin-echo, and chemical shift MR imaging accurately differentiate adrenal adenomas from malignant adrenal masses in patients with known malignancy?
Chemical shift imaging and calculated T2 values from echo-planar imaging are highly specific and sensitive for differentiating benign from malignant adrenal masses, potentially obviating the need for biopsy.
