However, this technique is associated with the risk of air embolism. We retrospectively evaluated whether small pulmonary nodules could be intraoperatively localized using cone-beam computed tomography (CBCT).\u0000\u0000\u0000METHODS\u0000A hybrid operating room permitting stable lateral positioning and scanning from the pulmonary apex to the base was used in all patients. CBCT images were obtained using a 10-s protocol with 180º rotation of the C-arm flat panel detector around the patient. Clips were placed on the visceral pleura to help guide pulmonary nodule localization. Partial pulmonary resection was performed using video-assisted thoracoscopic surgery at the predicted nodule site.\u0000\u0000\u0000RESULTS\u0000Between July 2013 and June 2019, 132 patients with 145 lesions underwent this procedure at our center. The detection rate of lesions on CBCT was 100%. The pathological diagnoses were primary lung cancer, metastatic pulmonary tumors, and benign lesions. The average consolidation-to-tumor ratio was 0.65 for all nodules, with ratios of 0.33, 0.96, and 0.70 for primary lung cancer, metastatic pulmonary tumors, and benign lesions, respectively.
