Description
Summary:Abstract Objective to compare the accuracy of CT and MRI in characterizing adrenal masses Materials And Methods 45 adrenal masses in 38 patients underwent unenhanced, enhanced CT and chemical-shift MRI. Sensitivities and accuracies using the lesion attenuation values, absolute or relative percentage washout for CT and adrenal-to-spleen ratio or signal intensity index for MRI. Follow up or histopathology as standard reference. Results 15 lipid rich adenomas, 6 lipid poor adenomas and 24 non-adenomas. The sensitivities for adenoma on MRI versus CT were 81%, 95% respectively. The specificities were 100%. Conclusion CT is superior to MRI in characterizing adenomas.
