Microwave ablation of hepatocellular carcinoma

Figure 1 Contrast-enhanced computed tomography scan shows, in the region surrounding what was the probe active tip position during the ablation (white arrow), an inner hyper-dense core contrasting with an outer thicker and hypo-dense annulus.

Figure 2 Time-lapse of ultrasound-guided percutaneous microwave ablation of medium-sized hepatocellular carcinoma of the right lobe. A: Ultrasound evaluation before ablation; B: Needle insertion; C: Hyperechoic boiling effect in the ablation area during the procedure; D: One month later ultrasound evaluation: The inner hyperechoic track corresponds to the position of the active probe.
