18F-FDG was also found superior to 68Ga-SSTR imaging in suspected metastasis or in the differentiation between pulmonary infections and ACTH-secreting bronchial tumors in found lung nodules [56,57], while 68Ga-SSTR appeared superior to 18F-FDG for de novo ECS tumor detection [51,57]. Here, POMC is linked to neoplasm.
