Figure 13: Case of metastatic lung carcinoma. ¹⁸F-FDG PET MIP images. (a) Prechemotherapy PET MIP images shows primary lesion with metastatic foci and axial fused PET-CT, (b) shows increased ¹⁸F-FDGuptakein right lung middle lobe with mediastinal lymphadenopathy, (c) images are postchemotherapy and MIP images shows significant decrease in size and metabolic activity of primary lesion and metastatic lesion, (d) fused axial PET-CT shows decrease in metabolic activity and extent ofd primary lesion, favouring partial response to the treatment. MIP: Maximum intensity projection, ¹⁸F-FDG: ¹⁸fluoride-fluorodeoxyglucose, PET: Positron emission tomography, CT: Computed tomography
