Computed Tomography-Navigation (TM) Electromagnetic System Compared to Conventional Computed Tomography Guidance for Percutaneous Lung Biopsy: A Single-Center Experience

{The aim of our study was to assess the efficacy of a computed tomography (CT)-Navigation (TM) electromagnetic system compared to conventional CT methods for percutaneous lung biopsies (PLB). In this single-center retrospective study, data of a CT-Navigation (TM) system guided PLB (NAV-group) and conventional CT PLB (CT-group) performed between January 2017 and February 2020 were reviewed. The primary endpoint was the diagnostic success. Secondary endpoints were technical success, total procedure duration, number of CT acquisitions and the dose length product (DLP) during step increment 1 (from planning to initial needle placement), step increment 2 (progression to target), and the entire intervention (from planning to final control) and complications. Additional parameters were recorded, such as the lesion's size and trajectory angles. Sixty patients were included in each group. The lesions median size and median values of the two trajectory angles were significantly lower (20 vs. 29.5 mm
