(68)Ga-DOTATATE PET/CT is the most sensitive tool in the detection of HNPGLs, especially SDHD-related tumors, which may be very small and fail to concentrate sufficient (18)F-FDOPA. The present study further expands the use of (68)Ga-DOTATATE for all patients with HNPGLs, regardless of their genotype. (68)Ga-DOTATATE PET/CT may be inferior to (18)F-FDOPA PET/CT in the detection PHEOs.

(18)F-DOPA PET/CT enables early diagnosis of a significant number of patients with distant metastasis. It has a limited sensitivity in the detection of residual disease but provides high performance for regional analysis. A surgical compartment-oriented approach could be the approach of choice whatever the number of nodes revealed by (18)F-DOPA PET/CT.
