From: An exploratory study of CT-guided percutaneous radiofrequency ablation for stage I thymoma
Illustration of the step-by-step puncture procedure and appearance immediately after ablation. The size of the thymoma was included to calculate the ablation time before puncture (a). After designing the puncture approach, the step-by-step puncture was performed from the surface to the tumor, as shown (b-i). Immediately after ablation, an additional CT scan was performed to identify residual lesion tissue (j, k and l). The lesion was completely ablated
