a, b One lesion was clearly seen in the lung window and mediastinal window, which was pathologically confirmed as squamous cell carcinoma by biopsy. c 3D reconstruction revealed the size and margin of the tumor (purple color). d, e 2 days after ablation, CT showed no pneumothorax and pleural effusion, and the ablation zone was visible. f 3D reconstruction revealed the ablation zone and spatial relationships of the tumor (purple color). g, h 10 months after MWA, the ablative zone shrink and fibrosis had developed. i The images of pr-ablation (c) and postablation (f) were fused and displayed as (i). Quantitative measurement shown the minimal ablative margin was > 5 mm
