Axial CT obtained (a) pretreatment: image in late arterial phase (AP) shows nonrim arterial phase hyperenhancement of a 3.5-cm LR-5 observation in segment VI (arrow). b 1 month post transarterial chemoembolization (TACE): image in portal venous phase shows ethiodized oil retention with optimal targeting (arrow). c 2 months post TACE: image in late AP shows decrease of ethiodized oil retention (arrow). Density of ethiodized oil limits the assessment at the anterior part of the lesion. The treated observation is categorized LR-TR Equivocal
