Hepatic focal lesion after TARE. a Subtracted enhanced T1-WI in the arterial phase shows faint enhancement of the treated right lobe (ROI 2 “orange”) compared to untreated hepatic parenchyma (ROI 1 “blue”). b T1 perfusion map (max. relative enhancement) shows mild increased blood flow to the treated right lobe. c Time-intensity curves on the treated right lobe (orange) and untreated left lobe (blue) show an uprising slope and followed by a plateau for the lesion due to fibrosis. d Semi-quantitative data for both ROIs show decreased max. relative enhancement, time to peak, wash in rate, and wash out rate of the treated hepatic parenchyma compared to the rest of the hepatic parenchyma. Final diagnosis is LR-TR nonviable with post-therapy changes
