Resumoscintigraphy with 111 In-pentetreotide, published by the Society of Nuclear Medicine [1] .99m Tc-Depreotide (Neotect ) is another commercially available somatostatin analog that has been approved specifically for the detection of lung cancer in patients with pulmonary nodules [2] .Because of the relatively high abdominal background and the impossibility of performing delayed imaging due to the short half-life of the tracer, it is less suited for the detection of abdominal neuroendocrine tumors [3] .Somatostatin is a regulatory peptide widely distributed in the human body, in particular in the central and peripheral nervous system, in the endocrine glands, in the immune system as well as in the gastrointestinal tract.In all these tissues, somatostatin action is mediated through membrane-bound receptors, of which five have been cloned (sst1-sst5) [4] .They all belong to the family of G-protein-coupled receptors.Only sst2, sst5 and, to some extent, sst3 have a high affinity for the commercially available synthetic octapeptide octreotide [5] .Somatostatin receptors are expressed in several normal human tissues, including brain, pituitary, gastrointestinal
