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...
BACKGROUND Effective dose represents the potential risk to a population of stochastic effects of ionizing radiation (mainly lethal cancer). In recent years, there have been a number of revisions and updates influencing the way to estimate the effective dose. The aim of this work was to recalculate the effective dose values for the 338 different radiopharmaceuticals previously published by the I...
99mTc-labeled hepatobiliary iminodiacetic acid (HIDA) scintigraphy is an important adjunct to the evaluation of patients with abdominal pain. The introduction of radiopharmaceuticals that allowed the performance of these studies in patients with elevated bilirubin levels expanded the clinical use of this important diagnostic imaging technology. The proper use of HIDA scintigraphy requires an un...
copper-64 was produced in large scales and high specific activities in late 1990s’ using compact cyclotrons based by 64ni(p,n)64cu reaction and many radiopharmaceuticals developed since then by various groups based on interesting physicochemical and nuclear properties of the radionuclide. the unique emission of beta particles as well as positron particles offers a spectacular real therapeutic/d...
