Radiation Therapy for Lung Cancer Imaging Appearances and Pitfalls

A strong understanding of radiation techniques, including CRT and SBRT, and the expected posttherapy imaging manifestations enables more confident and accurate interpretations of surveillance CT imaging studies in patients with prior RT. Knowledge of common complications and corresponding CT imaging appearances, particularly tumor recurrence and infection, leads to more accurate diagnoses, timely treatment, and avoidance of pitfalls in interpretation.
