Purpose: To investigate the influence of germline succinate dehydrogenase (SDHx) pathogenic variants on 6-[F]-fluoro-3,4-dihydroxyphenylalanine (F-DOPA) Positron Emission Tomography (PET) radiomic signature of head and neck paragangliomas (HNPGLs).
Methods: Forty-seven patients (20 SDH pathogenic variants carriers) harboring 55 HNPGLs were retrospectively included. HNPGLs were delineated using Nestle adaptive threshold.
Purpose: To investigate the [Ga]DOTATOC PET radiomic profile of head and neck paragangliomas (HNPGLs) and identify radiomic characteristics useful as predictors of succinate dehydrogenase genes (SDHx) pathogenic variants.
Methods: Sporadic and SDHx HNPGL patients, who underwent [Ga]DOTATOC PET/CT, were retrospectively included. HNPGLs were analyzed using LIFEx software, and extracted features were harmonized to correct for batch effects and confronted testing for multiple comparison.
