| pubmed-article:15518149 | pubmed:abstractText | For differentiation of benign and malignant adrenal lesions, sensitivities and specificities of 85-100% can be reached by unenhanced computed tomography (CT)-methods, chemical shift techniques in magnetic resonance imaging (MRI), delayed enhanced CT-techniques, and by evaluation of wash-out curves in contrast enhanced CT or MRI. An increasing number of adrenal lesions that are detected on imaging studies for indications unrelated to the adrenals can be immediately characterized by delayed series nowadays. According to excellent results of CT and MRI in characterization of adrenal masses, the indications for fine needle aspiration biopsy have already regressed as well as complications associated with this invasive technique. | lld:pubmed |
