Preoperative CT-guided localization of pulmonary nodules with low-dose radiation
BACKGROUND: Video-assisted thoracoscopic surgery (VATS) has been widely accepted for the treatment of pulmonary nodules. Prior to VATS, pulmonary nodules can be labeled by computed tomography (CT)-guided hook wire localization, but multiple scans are required, which increases the total radiation dos...

description | BACKGROUND: Video-assisted thoracoscopic surgery (VATS) has been widely accepted for the treatment of pulmonary nodules. Prior to VATS, pulmonary nodules can be labeled by computed tomography (CT)-guided hook wire localization, but multiple scans are required, which increases the total radiation dose. We aimed to assess the effectiveness and risks of using low-dose radiation CT to locate lung nodules prior to VATS. METHODS: This study included 158 patients who underwent VATS resection after CT-guided hook wire localization. Based on the CT tube voltage, patients were split into two groups: the low-voltage group (Group A) received 80 kV, while the high-voltage group (Group B) received 120 kV. The two groups’ image quality, radiation exposure, localization success and complication rates were compared. The frequencies of intraoperative complications and the types of lung nodules were also compared between the groups. RESULTS: Successful nodule mapping was obtained in 158 patients. There was no significant difference in age, sex ratio or BMI between the two groups. Subjective imaging quality in both groups met the requirements for location (≥2 points). The signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) in Group A were lower than those in Group B (P<0.05). Furthermore, the dose length product (DLP) and effective dose (ED) in Group A were lower than those in Group B (P<0.05). CONCLUSIONS: Low-dose radiation CT-guided localization is safe and feasible for identifying uncertain pulmonary nodules before VATS, enabling a significant radiation dose reduction while maintaining mapping accuracy and not increasing complication risk. |
