EP01.01. Radiation Exposure in Intraoperative Navigation for Peripheral Small Pulmonary Nodule - PDF(Abstract)

Pdf Summary

This study investigated the radiation exposure dose in a hybrid operating room (Hybrid-OR) equipped with cone-beam computed tomography (CBCT) for intraoperative navigation of small pulmonary nodules. The study included 97 patients who underwent surgery with intraoperative localization using CBCT. Wearable dosimeters were used to measure radiation exposure. The results of the study showed that the average radiation dose was 1.84 mGy, with a maximum exposure dose of 61.58 mGy. The number of CBCT scans was significantly correlated with the patient's exposure dose. The sandwich marking technique used for intraoperative identification was successful in 95.3% of cases within 3 CBCT scan times. The study concluded that it is important to minimize the number of scans in order to reduce radiation exposure in the future.
