Exceptional Visualization of the Gallbladder on 68Ga-DOTANOC PET/CT Imaging

Abstract

Neuroendocrine tumors (NETs) are rare tumors associated with the overexpression of somatostatin receptors owing to their origin from neural crest cells. The somatostatin receptor-based molecular imaging of NETs with 68 Ga-DOTANOC is extensively used to diagnose primary and metastatic disease with high diagnostic accuracy. Unlike conventional octreotide imaging, physiological gallbladder uptake is not seen on 68 Ga-DOTANOC PET/CT imaging. The present case report exhibits the rare physiological 68 Ga-DOTANOC uptake in the gall bladder and bile duct.
