introduction:owing to its favorable radionuclidic characteristics, such as tl/2 = 6.73 day and eβ (max) = 497 kev and ease of its large-scale production using medium flux research reactors, lutetium-177 (177lu) is an attractive radionuclide for various therapeutic applications. no carrier added (nca) 177lu was obtained by thermal neutron bombardment (4×1013n/cm2.s) of 176yb target through 176yb...

Background: In internal radiation therapy of cancer, optimal targeting ligand and type therapeutic radionuclide must be considered carefully for effective treatment. addition, nuclide may vary depending on diverse parameters characterizing the tumor. Thus, use in various cancers, there is a need development carrier that can firmly bind to variety nuclides. Here we introduce biocompatible iron o...

The present study examines the extent of spinal cerebrospinal fluid (CSF) absorption in healthy individuals in relation to physical activity, CSF production, intracranial pressure (ICP), and spinal CSF movement. Thirty-four healthy individuals aged 21-35 yr were examined by lumbar puncture and radionuclide cisternography with repeated imaging. ICP was registered before and after CSF drainage, a...

The detection of regional asynergy provides strong evidence for a critical reduction of coronary blood flow to that zone. In the present study, the usefulness of combining computer-assisted radionuclide angiography and isometric handgrip exercise testing to detect coronary heart disease (CHD) was evaluated. One hundred twenty-nine patients with chest pain undergoing cardiac catheterization were...
