Introduction: Nowadays, radioisotopes have a lot of therapeutic and diagnostic applications in nuclear medicine. The technetium-99m radioisotope is widely used in the diagnostic field. The technetium-99m radioisotope is widely used in the diagnostic field. In this study, in order to increase the absorption dose in thyroid cancer cells, the radioactive drug technetium-99m which ...

Background: Technetium-99m radioisotope is the backbone of any nuclear medicine institute. This radioisotope is acquired by the elution of Molybdenum-99/Technetium-99m generator which emits 141 keV gamma ray and having 6.04 hour half-life. Occasionally the contents of Molybdenum-99 may mix up with elute, which may affect image quality and patients may receive higher doses than recommended. This...

introduction: the endemic occurrence of new strains of tuberculosis around the globe has initiated new research on developing diagnostic radiopharmaceutical based on antibiotics. methods:tc-99m labeled streptomycin was prepared using freshly milked 99mtco4- and various concentrations of streptomycin, stannous chloride at various temperatures in high yield radiochemical purity shown by hplc/rtlc...

OBJECTIVE A subset of parathyroid adenomas contains a relative overabundance of oxyphil cells that are capable of greater technetium Tc 99m sestamibi tracer uptake and retention than other cell types. We examined whether the presence of oxyphil cells augments the sensitivity of technetium Tc 99m sestamibi preoperative localization and whether the histologic findings of a lesion could be predict...

A 22-year-old female patient with severe hypertension underwent both Technetium-99m diethylenetriaminepentaacetate and Technetium-99m mercaptoacetyltriglycine basal and captopril renal scintigraphy. While no significant change was seen with Tc-99m DTPA, there was left sided parenchymal retention of captopril Tc-99m MAG3 suggesting renal artery stenosis which was confirmed by angiography.

Key words: hyperparathyroidism-radionuclide-imaging; primary and secondary hyperparathyroidism [1–3]. With hyperplastic parathyroid glands tetrofosmin hyperplasia; Technetium-99m-diagnostic use; tetrofosmin imaging gives an overall sensitivity of 84% and a specificity of 75%, higher than those of Tc-99m sestam-ibi, ultrasonography and magnetic resonance imaging Renal history [1–2]. The former h...

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...
