Ga-68 Labeled Somatostatin Analogs Positron Emission Tomography/ Computed Tomography in Gastroenteropancreatic Neuroendocrine Tumors
Neuroendocrine tumors (NETs) are characterized by the heterogeneous nature, frequently indolent course and possibility of multiple and variable anatomic sites of the primary tumor. Somatostatin is a cyclic peptide consisted of 14 amino acids and produced by neuroendocrine, immune, and inflammatory cells. The cerebral cortex, the brain stem, the hypothalamus, the pancreas and the gastrointestina...
متن کاملAdditional information gained by positron emission tomography with (68)Ga-DOTATOC for suspected unknown primary or recurrent neuroendocrine tumors.
OBJECTIVE Positron emission tomography (PET)/computed tomography (CT) using (68)Ga-labeled 1,4,7,10-tetraazacyclododecane-N,N',N″,N‴-tetraacetic acid-D-Phe(1)-Tyr(3)-octreotide (DOTATOC) has been used to detect neuroendocrine tumors (NETs). The purpose of this study was to investigate the clinical efficacy of DOTATOC-PET/CT for detecting clinically suspected NETs when conventional imaging modal...
متن کاملAn overview on Ga-68 radiopharmaceuticals for positron emission tomography applications
Gallium-68 a positron emitter radionuclide, with great impact on the nuclear medicine, has been widely used in positron emission tomography (PET) diagnosis of various malignancies in humans during more recent years especially in neuroendocrine tumors (NETs). The vast number of 68Ge/68Ga related generator productions, targeting molecule design (proteins, antibody fragments,...
متن کاملDetection of paranasal ectopic adrenocorticotropic hormone-secreting pituitary adenoma by Ga-68-DOTANOC positron-emission tomography-computed tomography.
Ectopic adrenocorticotropic hormone (ACTH)-secreting tumors account for approximately 10% of Cushing's syndrome (CS). We present an extremely rare case of a patient with CS caused by an ectopic ACTH-secreting pituitary adenoma (EAPA) of the ethmoid sinus. The tumor was identified by positron-emission tomography-computed tomography (PET/CT) using the somatostatin receptor analogue Ga-68-DOTANOC....
متن کاملA Comparative Study of the Construction of Positron Emission Tomography/Computed Tomography Facilities in Three South African Hospitals
Introduction: Development of higher energy modalities such as positron emission tomography/computed tomography (PET/CT), has led to more complex shielding problems. This is due to several factors, such as the radiopharmaceutical relatively high-administered activity, high patient throughput, and high energies of 511 kilo-electron volt (keV) positron annihilation photon...
