LUNG CANCER
In recent years, computed tomography (CT) screening for lung cancer has become a routine examination [Compared to CT-guided biopsy for lung masses, biopsy for PNs is a more difficult technique due to the smaller lesion size. Therefore, when performing CT-guided biopsy for PNs, prolonged CT scans are usually required to adjust the needle position and angle [In this study, we conducted an RCT to evaluate the relative safety and diagnostic performance of low- and standard-dose CT-guided biopsy for PNs.
