68Ga-DOTATOC PET/CT Uptake and Physiological Impairment in DIPNECH: An Exploratory Case Series

Background/Objectives: Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) can cause respiratory symptoms and physiological impairment. We explored whether quantitative somatostatin-receptor imaging by positron emission tomography/computed tomography with gallium-68-labelled DOTATOC (68Ga-DOTATOC PET/CT) is associated with pulmonary physiology and nodule count in histologically confirmed DIPNECH.
