Figure 8 Transverse CT scans obtained in a 71-year-old woman with HCC in the hepatic dome. (a) Early-phase scan obtained before PEI shows a 1.4-cm nodule (arrow) in the anterosuperior segment of the liver. (b) At CT fluoroscopy, two needles were inserted into the nodule with a right-sided approach, and 10 ml of absolute ethanol was injected. (c) Early-phase scan obtained 1 year after PEI shows no enhancement (arrowhead) in the tumor area.

Figure 10 Transverse CT scans obtained in a 65-year-old woman with a recurrent nodule after transcatheter arterial embolization. (a) Early-phase scan obtained before PEI shows a 2.3-cm recurrent nodule (arrows). (b) A PEI needle was introduced into the nodule with the coaxial method, and 10 mL of ethanol was injected with CT fluoroscopic guidance. ChestCT scan (not shown) obtained immediately after PEI showed no pneumothorax or pleural effusion.
