Introduction: Appendicitis is one of the most common surgical emergencies. In spite of the relatively high rate of negative appendectomy, as a result of miss diagnosis, uncertainty of diagnosis still continues to challenge physicians. The objective of this prospective study was to investigate the role of 99mTc-Ubiquicidin (UBI) scintigraphy in the diagnosis of acute appendicitis and ...
(99m)Tc-HYNIC-annexin A5 can be considered as a benchmark in the field of apoptosis imaging. However, (99m)Tc-HYNIC-annexin A5 has characteristics of high uptake and long retention in non-target tissues such as kidney and liver. To minimize this problem, we developed a novel (99m)Tc-labeled annexin A5 using a bis(hydroxamamide) derivative [C3(BHam)2] as a bifunctional chelating agent, and evalu...
Parathyroid adenoma involving a single parathyroid gland is the underlying cause of 80-85% of primary hyperparathyroidism (PHPT). Skeletal system is significantly affected by PHPT. Brown tumors are known to have affinity for 99mTc-MIBI. We report a rare case of PHPT presenting with diffuse bony pain, high calcium level and significantly elevated alkaline phosphatase level. 99m<...
UNLABELLED Reliable assessment of hepatic function during liver regeneration is crucial after liver surgery or liver transplantation. (99m)Tc-galactosyl human serum albumin ((99m)Tc-GSA) scintigraphy, (99m)Tc-mebrofenin hepatobiliary scintigraphy (HBS), the indocyanine green (ICG) clearance test, and the galactose elimination capacity (GEC) are common quantitative liver function tests. However,...
Introduction: This report describes the synthesis of 2-Amino-2-deoxy(S-benzoylthioacetyl)-D-glucose (S-Bz-TA-DG), radiolabeled with [99mTc(CO)3(OH2)3]+ complex with a procedure including deprotection of the benzoyl group, characterization by HPLC using a C18 reverse phase column and preliminary biodistribution study in normal ...
UNLABELLED The imaging of neuroendocrine tumors has become one of the most significant areas in nuclear oncology. In an attempt to provide high-quality imaging and possible sensitivity at a reduced cost, time, and radiation dose, several (99m)Tc agents have been proposed. The aim of this initial study was to compare the tumor uptake and biodistribution of 2 new 6-hydrazinopyridine-3-carboxylic ...
Two deoxyglucose (DG) derivatives, (α,β)-2-deoxy-2-amino(ethylcarbamate)-D-glucose (ECB-DG) and (α,β)-2-deoxy-2-amino(1,2-dihydroxypropyl)-D-glucose (DHP-DG), were synthesized and radiolabeled successfully with [(99m)Tc(H2O)3(CO)3](+) complex. [(99m)Tc]-ECB-DG and [(99m)Tc]-DHP-DG complexes were prepared (96% and 93% radiochemical purities respectively) by using 46 mCi of Na(99m)TcO4 in 1 mL sa...
Despite the long history of worldwide use of bacillus Calmette-Guerin (BCG) vaccine, a wide spectrum of adverse reactions has been observed in a small proportion of immunized infants. The most severe complication is disseminated BCGitis, often fatal but extremely rare and considered to be a result of host immunodeficiency. At present, polymerase chain reaction test, CT scan, ultrasound, X-rays ...
