Zidan et al. employed a similar scale in a retrospective cohort of 56 patients with biopsy‐proven Typical carcinoid (TC; 22/56) and Atypical carcinoid (AC; 34/56), studied with both 68Ga‐DOTATATE and FDG (score 1: if all lesions were negative on both tracers, score 2: if all lesions were SST‐positive/FDG‐negative, score 3: if all lesions were SST‐positive but some/all were spatially concordant FDG‐positive, score 4: spatially discordant FDG‐positive and SST‐negative lesions). This evidence concerns the gene SST and carcinoid tumor.
