Introduction In nuclear medicine, diagnostic imaging displays the metabolic function of the human body. The radiopharmaceuticals enable cancer imaging as unbound isotopes or simple compounds, non target tracers, target tracers and target cancer radiopharmaceuticals (1). Molecular imaging strategies of PET radiopharmaceuticals and combined technology of PET-CT have a major role in oncology today...
Combining two or more different imaging modalities in the same agent can be of considerable value in molecular imaging. We describe the use of streptavidin nanoparticle-based complexes as multimodality imaging agents to achieve tumor detection in a mouse model by both fluorescence and nuclear imaging. Up to four biotinylated functionalities can be readily attached to these streptavidin nanopart...
Objective(s): In recent years, the application of radiopharmaceuticals in nuclear medicine has increased substantially. Following the diagnostic procedures performed in nuclear medicine departments, such as myocardial perfusion imaging, patients generally receive considerable doses of radiation. Normally, radiation-induced DNA damages are expected following exposure to a low-dose ionizing radia...
Weapons-grade uranium and plutonium could be used as nuclear explosives with extreme destructive potential. The problem of their detection, especially in standard cargo containers during transit, has been described as "searching for a needle in a haystack" because of the inherently low rate of spontaneous emission of characteristic penetrating radiation and the ease of its shielding. Currently,...
