Low-Dose Computed Tomography (LDCT) screening for Lung Cancer (LC) is currently suggested (grade of recommendation = 2B); nevertheless, radiation exposure and costs are still a problem. In Baseline results of SOS study, single-arm observational study of chest Digital Tomosynthesis (DT) in a LC at-risk population, we have shown a LC detection rate comparable to LDCT (0.98%), low effective radiation dose (0.13 mSv), and 1/6 cost of LDCT. DT is limited angle tomography that allows reconstruction of multiple image planes and provides high-resolution images in coronal planes. We present the results of the SOS study.
