Alteration of tumor lesions before and after chemoembolization by hepatic CT. All images are from the same patient. (A) Tumors showed ring enhancement before embolization; (B) 3 days after embolization, re-examination by CT showed honeycomb-like necrosis of tumor tissue; (C) tumors displayed shrinkage 1 month after embolization, without intensification in the lesions; (D) 3 months after embolization, more profound tumor shrinkage was visible.
