Figure 14: Case of nasopharyngeal carcinoma. ¹⁸F-FDG PET MIP images (a and b) prechemotherapy PET MIP images and axial fused PET-CT images shows increased 18F-FDG uptake in right nasopharynx with extensions to contralateral sides. (c and d) Images are postchemotherapy and shows significant decrease in size and metabolic activity of primary lesion, favouring partial response to the treatment. MIP: Maximum intensity projection, ¹⁸F-FDG: ¹⁸fluoride-fluorodeoxyglucose, PET: Positron emission tomography, CT: Computed tomography
