An intrapatient comparison of 99mTc-EDDA/HYNIC-TOC with 111In-DTPA-octreotide for diagnosis of somatostatin receptor-expressing tumors.
UNLABELLED The aim of this study was to compare the imaging abilities of the recently developed somatostatin analog, (99m)Tc-hydrazinonicotinyl-Tyr(3)-octreotide ((99m)Tc-HYNIC-TOC [(99m)Tc-TOC]), with (111)In-diethylenediaminepentaacetic acid-D-Phe(1)-octreotide ((111)In-OCT [Octreoscan]) in patients undergoing routine somatostatin receptor (SSTR) scintigraphy. METHODS Forty-one patients (20...
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 کاملSynthesis, labeling, formulation and quality control of 99mTc-Tricine-HYNIC-Tyr³-Octreotide, a peptide radiopharmaceutical for imaging Somatostatin receptor positive tumors [Persian]
Somatostatin analoges labeled with different radionuclides are able used for imaging and treatment of somatostatin receptor positive tumors. In this study Tyr³-Octreotide protected at lysine as an analoge of somatostatin was conjugated with bifunctional chelating agent 6-BOC-hydrazinopyridine-3-carboxylic acid (BOC-HYNIC) and after deprotecting of conjugate, purification was performed wit...

از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...
15 صفحه اولClinical utility of indigenously formulated single-vial lyophilized HYNIC-TOC kit in evaluating Gastro-entero Pancreatic neuro endocrine tumours
Objective(s): The objective of this study was to evaluate the performance and utility of 99mTc HYNIC-TOC planar scintigraphy and SPECT/CT in the diagnosis, staging and management of gastroenteropancreatic neuroendocrine tumors (GPNETs). Methods: 22 patients (median age, 46 years) with histologically proven gastroentero-pancreatic NETs underwent 99mTc HYNIC-TOC whole body scintigraphy and regi...
