introduction: to retrospectively analyze the outcome of patients who underwent meckel’s scan in a local centre in hong kong over the past fifteen years. diagnostic values in different referring indications were also reviewed. methods: all patients who referred for meckel’s scan in a local hospital in hong kong from 1/1/1996 to 31/12/2010 were identified. patients’ demographic data, presenting s...

introduction: this study was done to determine the site of obstruction in lacrimal drainage system in asian patients suffering from epiphora and to determine the transit time taken for the tracer material to reach the lacrimal sac and the nasal cavity. methods:dacryoscintigraphy was performed using radionuclide technetium-99m pertechnetate (99mtc) in 34 patients suffering from unilateral or bil...

Technetium-99m dimercaptosuccinic acid (DMSA) scan was performed on a 32-year-old woman with 
 abdominal pain. A normal functioning slightly ptotic right kidney seen planar images. There no activity in the left renal region and small fusiform pelvic area. Pelvic computed tomography (CT) axial images revealed pre-vesical abscess pushing bladder posteriorly to side. On obtained after percuta...

NaRe$_2$(PO$_4$)$_3$ phosphate-based ceramic with the structure of kosnarite mineral was obtained by spark plasma sintering. Rhenium (Re) served as a chemical and structural analog technetium. The relative density 85%. mechanism Re static leaching from at room temperature investigated. rate rhenium $1.3\times10^{-5}$ g/(cm$^2$*day).

The authors present a case of subhyoid ectopic thyroid with mediolateral location diagnosed by technetium-99m pertechnetate scan. The ectopia was associated with hypothyroidism and developmental retardation.

As part of its responsibilities under various Acts of Parliament, MAFF Directorate of Fisheries Research has a duty to carry out a substantial programme of monitoring, surveillance and research in relation to the quality of the aquatic environment in and around the United Kingdom. In the course of that programme, a wide variety of methods of analysis are used for a wide variety of contaminants,...

Technetium-99m (99mTc) is one of the most desirable radionuclides for external imaging in diagnostic nuclear medicine, due to the emission of gamma ray of optimal energy (140 keV), a suitable half-life (6 h), and availability from 99Mo-99mTc generator systems. In addition, development of 99mTc radiopharmaceuticals for tumor imaging paves the way for therapeutic radiopharmaceuticals with high en...
