This study reinforced evidence for the reliability of CT attenuation value. Even with a simple method that can be performed by non-radiologists, CT attenuation values were highly reliable and useful for excluding malignancy and pheochromocytoma. In addition, all lesions in this study were evaluated both endocrinologically and pathologically, giving high validity to the reference standard. These findings complement and further substantiate the latest clinical practice guidelines of the European Society of Endocrinology.
