C-arm Lipiodol CT in transcatheter arterial chemoembolization for small hepatocellular carcinoma

Figure 1 Imaging findings in a 50-year-old man diagnosed with hepatocellular carcinoma. Re-examination after transcatheter arterial chemoembolization (TACE). A: No clear lesion was found on pre-procedure 64-slice CT; B: No clear tumor staining was found following digital subtraction angiography examination; C: C-arm Lipiodol computed tomography (CT) scan after diagnostic embolization. A new Lipiodol lesion was found in the 6^th liver segment; D: Gelfoam particles were injected into the tumor-nourishing blood vessel; E: New hepatocellular carcinoma lesion in the 6^th segment was confirmed by CT examination performed 12 d after TACE.
