Chemokine receptor CXCR4 is a key factor for tumor growth and metastasis in several types of human cancer. This study investigated the feasibility of CXCR4-directed imaging of small cell lung cancer (SCLC) with positron emission tomography/computed tomography (PET/CT) using the radiolabelled chemokine ligand [68Ga]Pentixafor. 10 patients with primarily diagnosed (n=3) or pre-treated (n=7) SCLC ...
Indium 111 DTPA Octreotide (Octreoscan) has been the pillar of Somatostatin receptor (SSTRs) imaging in nuclear medicine for over three decades. The advent PET/CT brought new analogs somatostatin that have higher affinity and improved resolution due to their labeling Gallium 68 positron imaging. most used include DOTATATE, DOTATOC DOTANOC. However, 68–1,4,7,10-tetraazacyclododecane-1,4,7,10-tet...
Through diagnostic imaging and peptide receptor radionuclide therapy, nuclear medicine has earned a major role in gastroenteropancreatic neuroendocrine tumors (GEP NETs). GEP NETs are diagnosed fortuitously or on the basis of symptoms or hormonal syndrome. The functional tumor characteristics shown by radionuclide imaging allow for more accurate staging and treatment selection. Tumor grade help...
Neuroendocrine tumours (NETs) have distinct biological and clinical characteristics, in particular a high density of somatostatin receptors at the cell membrane [1]. It is this property that allows the use of radiolabelled somatostatin analogues for imaging of these tumours. Importantly, somatostatin receptor PET/CT imaging (e.g. Ga-DOTATOC, Ga-DOTATATE, Ga-DOTANOC) is superior to somatostatin ...
