A 50-year-old woman was diagnosed with squamous cell carcinoma in the right external ear. The top and bottom images show fused images of 18F-FDG PET/CT and those of 18F-BPA PET/CT, respectively. The solid line with red, yellow, and green indicates the contour of GTV, MTV40, and MTV50, respectively. The discrepancy (white arrows) between two tracers is observed in coronal and sagittal planes due to physiological brain accumulation or inflammation (mastoiditis or external otitis)
