Figure 2: Synchronous procedure. (a) Computed tomography image showing a single peripheral nodule (arrow), 15 mm × 10 mm, in the posterior segment of the left upper lobe with inhomogeneous density, irregular margin, and pleural tail sign. (b) Computed tomography scan showing a coaxial introducer needle (arrow) which was placed abutting the lesion. (c) An ablative antenna (short arrow) was placed through the coaxial cannula (long arrow) into the nodule after biopsy. (d) In the thoracic computed tomography scan immediately after ablation, the ablated nodule presented with a circular ground-glass opacity (arrows)
