Summary
Brief summary (as posted)
To assess the RELIABILITY in terms of accuracy of 3D-CT and 2D-CT reconstructions compared to intraoperative data regarding bronchovascular anatomy and tumor location. 3D CT reconstruction (CT scan without contrast injection) with Innersight3D® is equivalent to 2D CT (CT scan with contrast injection) for planning a minimally invasive lung segmentectomy. Evaluate the impact of 3D reconstruction (from a CT scan without injection of contrast agent) on intraoperative and postoperative results

Inclusion Criteria: * Adult patient ≥ 18 years * Patient agreeing to participate in the study * Patient with clinical stage IA lung lesions ≤ 2 cm in diameter AND a suspected or proven malignancy. * Chest CT scan available without and then with contrast * Eligible for VATS or RATS segmentectomy based on respiratory explorations Exclusion Criteria: * Patient refusal to participate in the study * Allergic reactions to radiographic contrast agents * History of ipsilateral cardiothoracic surgery * Open segmentectomy (thoracotomy) * Histology different from that of NSCLC * Inability to provide the subject with informed information (difficulty understanding the subject, insufficient command of French, etc.) * Pregnant or breastfeeding women * Severe cognitive impairment and/or suspicion of lack of compliance or adherence, in the investigator's judgment
