Impact of segmentation and discretization on radiomic features in (68)Ga-DOTA-TOC PET/CT images of neuroendocrine tumor

OBJECTIVE: To identify the impact of segmentation methods and intensity discretization on radiomic features (RFs) extraction from (68)Ga-DOTA-TOC PET images in patients with neuroendocrine tumors. METHODS: Forty-nine patients were retrospectively analyzed. Tumor contouring was performed manually by...
