Efficacy and safety of computed tomography-guided microwave ablation with fine needle-assisted puncture positioning technique for hepatocellular carcinoma

Figure 3 Computed tomography-guided microwave ablation under fine needle-assisted puncture technique for a patient with hepatocellular carcinoma nodule in segment 5 accepted transarterial chemoembolization pre-microwave ablation. A: A 21-gauge fine needle of 15 cm length was inserted near the tumor nodule after computed tomography scanning before ablation needle puncture; B: A microwave electrode needle was gradually inserted inside the tumor according to the mark of the fine needle; C: The second microwave electrode needle was gradually inserted inside the tumor needle and approximately 1 cm beyond the tumor margin according to the mark of the fine needle; D: The complete ablation was confirmed by magnetic resonance imaging 2 mo post-microwave ablation.
