Imaging of ¹⁸ F-fluoro-2-deoxy-D-glucose positron emission tomography at baseline and after chemotherapy. (A) 2-[¹⁸F]-fluoro-2-deoxy-D-glucose positron emission tomography shows increased accumulation in the mediastinal lymph node (white arrow). (B) After one cycle of carboplatin plus etoposide, a positron emission tomography scan reveals a marked decrease in 2-[¹⁸F]-fluoro-2-deoxy-D-glucose uptake in the corresponding lesion (white arrow).
