Patient-specific dosimetry of 99mTc-HYNIC-Tyr3-Octreotide in children
BACKGROUND Technetium-99m-hydrazinonicotinamide-Tyr3-octreotide (99mTc-HYNIC-TOC) is recognized as a promising radiopharmaceutical for diagnosing neuroendocrine tumors (NETs). However, 99mTc-HYNIC-TOC dosimetry has been investigated only for adults. As pediatric radionuclide therapies become increasingly common, similar dosimetric studies for children are urgently needed. The aim of this study ...
متن کاملComparing diagnostic performance of 131I-metaiodobenzylguanidine (131I-MIBG) and 99mTc-hydrazinonicotinyl-Tyr3-Octreotide (99mTc-HYNIC-TOC) in diagnosis and localization of pheochromocytoma and neuroblastoma
Introduction: The present study was aimed to assess the diagnostic performance of the two imaging methods of 131I-metaiodobenzylguanidine (131I-MIBG) and 99mTc-hydrazinonicotinyl-Tyr3-Octreotide (99mTc-HYNIC-TOC) in diagnosis and localization of pheochromocytoma and neuroblastoma. Methods: This study ...
متن کاملevaluation and comparison of different quality control methods in radiochemical purity determination of new peptide kits 99mtc-edda-tricine-hynic-tyr3-octreotide and 99mtc-edda-tricine-hynic-tyr3-octreotate for imaging somatostatin receptor positive tumors [persian]
introduction: using labeled peptides enjoys high importance in nuclear medicine. somatostatin analogs labeled with different radionuclide are vastly investigated for diagnosis or treatment of somatostatin receptor positive tumors. labeling somatostatin analogs with 99mtc as alternative of 111in needs doing different quality control method for determination of labeling yield and complex stabilit...
متن کاملPreparation, formulation and quality control of one step kit 99mTc- EDDA/HYNIC-Tyr3-Octreotide as a peptide radiopharmaceutical for imaging somatostatin receptor positive tumors [Persian]
The high expression of somatostatin receptors in many tumours, have made receptor scintigraphy with 111In-DTPA-Octreotide a widly used procedure in nuclear medicine. Despite its clinical success, some limitation and drawbacks of radiolabelling with 111In remain, especially those concerned with the cost, availability and physical decay properties of this radionuclide. 99mTc-EDDA/HYNIC-Tyr3...
متن کاملSomatostatin receptor imaging in patients with neuroendocrine tumors: not only SPECT?
In this issue of The Journal of Nuclear Medicine, Gabriel et al. (1) report their experience with 68Ga-labeled 1,4,7,10tetraazacyclododecane-N,N9,N99,N999tetraacetic acid-D-Phe1-Tyr3-octreotide (68Ga-DOTA-TOC) PET in a series of 84 patients with neuroendocrine tumors (NET). PET was more accurate with a higher detection rate than somatostatin receptor scintigraphy (using 111In-DOTA-TOC or 99mTc-...
