摘要

We investigate the diagnostic reliability of differentiating between lipid-poor adrenal adenomas and metastatic adrenal tumors originating from hepatocellular carcinoma (HCC) using a routine dynamic CT protocol for liver imaging. Eighteen metastatic adrenal tumors originating from HCC and 13 lipid-poor adrenal adenomas were identified. Dynamic CT data were analyzed for CT attenuation of adrenal lesions before and after contrast administration. When a cutoff of 36 HU was set for adrenal lesions at pre-contrast attenuation, the sensitivity and specificity for the diagnosis of metastatic lesions were 94.4%and 92.3%, respectively. Attenuation criteria on pre-contrast CT may help optimize the differentiation between these lesions.
