Head-to-head comparison between 18 F-FDOPA PET/CT and MR/CT angiography in clinically recurrent head and neck paragangliomas

Conclusion18F-FDOPA PET/CT is highly sensitive in posttreatment evaluation of patients with HNPGLs, and also offers better interobserver reproducibility than MRA/CTA and whole-body examination. We therefore suggest that18F-FDOPA PET/CT is performed as the first diagnostic imaging modality in symptomatic patients with suspicion of HNPGL relapse after primary treatment when68Ga-labeled somatostatin analogues are not available.
