Abstract:
Intraoperative localization of ground-glass opacities is difficult because they are not easy to palpate and may be invisible at radioscopy. Therefore, various techniques have been developed to improve intraoperative localization of these lesions, allowing an adequate surgical resection. The aim of this study is to report two cases of preoperative localization of ground-glass opacities through computed tomography-guided placement of a metallic clip inside the lesion and to discuss this new technique in comparison with those previously described.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
