The ACR White Paper on Incidental Findings [1] has provided an outstanding evidence- and expert consensus–based approach for incidental lesions that are commonly encountered in prac-tice.

Enhancing liver lesions can be characterized as ei-ther hypovascular or hypervascular, with the latter group being distinguished by earlier, more intense enhancement relative to normal hepatic paren-chyma. Thus, accurate detection of hypervascular liver masses requires dynamic contrast-enhanced imaging during the hepatic arterial phase, whereas

for most incidental lesions in our algorithm, radiologists should seek to identify definitively benign features to prevent unnecessary follow-up imaging. The most commonly encountered benign hepatic le-sions fall into four major categories: hepatic cysts, perfu-sional changes, hemangiomas, and focal nodular hyperplasias (FNHs) [39-41].
