Ablation techniques for primary and metastatic liver tumors

Figure 1 Sixty-eight-year-old male with hepatitis C and cirrhosis. A: Contrast enhanced CT shows a 16 mm HCC; B: RFA probe covering the lesion; C: Post contrast follow up CT shows capsular retraction at the site of the RFA and no residual tumor. HCC: Hepatocellular carcinoma; RFA: Radiofrequency ablation; CT: Computed tomography.

Figure 2 Sixty-one-year-old with a history of alchohol abuse and cirrhosis. A: MRI demonstrates a 13 mm HCC in the left lobe; B: Two cryoablation probes covering the lesion; C: Post contrast follow up MRI shows capsular retraction at the site of the cryoablation and no residual tumor. MRI: Magnetic resonance imaging; HCC: Hepatocellular carcinoma.

Figure 3 Sixty-two-year-old with hepatitis C cirrhosis. A: MRI shows an arterial enhancing lesion consistent with hepatocellular carcinoma; B: CT guided microwave ablation of the right hepatic lobe lesion; C: MRI shows an ablation zone and no evidence of residual tumor. MRI: Magnetic resonance imaging; CT: Computed tomography.
