Axial CT in late arterial phase obtained (a) pretreatment: image shows arterial phase hyperenhancement (APHE) of a nodule (arrow) within previous drug-eluting beads TACE (DEB-TACE) treatment zone. b 1 month post repeat DEB-TACE: image shows APHE of a 3 mm focus (arrow) at periphery of treatment zone. At this point, the treated observation is categorized LR-TR equivocal. c 4 months post repeat DEB-TACE: image shows enlarging 14 mm nodular APHE (arrow) at periphery of treatment zone.
