Penangkapan non-osseous pada pemeriksaan sidik tulang dengan menggunakan radiofarmaka Technetium-99m methylene diphosphonate (Tc-99m MDP) dapat disebabkan karena proses neoplasma, trauma, inflamasi, iskemik, dan artefak. Perubahan metabolisme lesi diketahui pencitraan Tc-99m MDP. Lesi jaringan lunak terlihat adanya peningkatan aktivitas area fokal. Tujuan penulisan telaah pustaka ini adalah unt...

Despite recent advances in therapeutic and diagnostic approaches, coronary artery disease (CAD) and its related cardiac disorders represent the most common cause of death in the United States. Nuclear myocardial perfusion imaging (MPI) technologies play a pivotal role in the diagnosis and treatment design for CAD. Recently, in order to develop improved MPI agents for diagnosis of CAD, (99m)Tc-[...

The technetium-99m complex of the L,L-ethylenedicysteine diethylester (EC), of the brain imaging agent, was reported as a good choice for replacement of the renal nuclear medicines like OIH radiopharmaceutical. This present research work studies the structural, electronic and spectral properties of the EC compound and its complex with technetium-99m radionuclide from theoretical insight. All co...

BACKGROUND AND THE PURPOSE OF THE STUDY Technetium-99m is the major radionuclide used in the world and mainly is provided by fission product. However extensive research has been conducted on the use of accelerators for production of (99m)Tc. This investigation reports the production of (99m)Tc radioisotope using cyclotrons and the preparation, quality control and biodistribution studies of four...

Objective- To consider the use of renal scintigraphic evaluation of kidney function in Persian cat and make a comparison between 99mTechnetium ethylenedicysteine and 99mTechnetium diethylenetriaminepentaacetic in renal scintigraphy. Design- Descriptive study Animals- 6 male healthy adult Persian cats - no clinical sign of renal disorders and prior to presentation. Proce...

This first clinical prospective study was conducted to use of technetium-99m immunoglobulin G ((99m)Tc-IgG) as compared with autologous (99m)Tc-red blood cells (RBC) in gated blood pool ventriculography. We studied 12 patients who referred to us for a possible diagnosis of liver hemangioma or infection. Six patients underwent gated planar blood pool (GPBP) acquisition using (99m)Tc-RBC and 6 GP...

DMSA (meso-2,3-dimercaptosuccinic acid) adalah suatu senyawa dengan gugus sulfhydryl yang mampu berikatan secara chelation berbagai logam berat. Awalnya dimanfaatkan sebagai antidotum keracunan berat, namun seiring berjalannya ilmu pengetahuan, berhasil ditandai menggunakan Tc-99m Pertechnetate dan dimaanfaatkan luas dalam bidang kedokteran nuklir. scan telah digunakan nefrourologi, terutama un...

UNLABELLED Many groups have reported the adsorption or retention of (99m)Tc-radiopharmaceuticals on injection vials and disposable plastic syringes. Such an enormously high loss of radioactivity would result in poor images, radiation exposure, waste, and economic burdens. We therefore decided to investigate the extent of adsorption or retention of several (99m)Tc-radiopharmaceuticals on injecti...

The authors report and discuss a case of bilateral renal artery stenosis in a hypertensive 9 year-old girl that was first suspected with Technetium-dimercaptosuccinic acid renal scintigraphy. The scintigraphy showed signs of acute renal failure while the patient was on enalapril for controlling her hypertension. Bilateral renal artery stenosis was confirmed with computed tomography angiography....

6-Hydrazinonicotinic acid (HYNIC, 1) is a well-established bifunctional technetium-binding ligand often used to synthesise bioconjugates for radiolabelling with Tc-99m. It is capable of efficient capture of technetium at extremely low concentrations, but the structure of the labelled complexes is heterogeneous and incompletely understood. In particular, it is of interest to determine whether, a...
