Synthesis, Characterization, In Vitro and in vivo MR Studies of Dy (OH) 3 Nanostructures for T2 MRI Contrast Agent

摘要: Dy-compounds are promising candidates for MRI contrast agent. Dy 3+ has the shortest electronic relaxation time and highest magnetic moment (10.6 B) which induce water proton relaxation that primarily affect T 2. It increases significantly with the external magnetic field, and is proportional to the square of the magnetic moment of the Dy 3+ ion. Dy (OH) 3 nanostructures were examined for their possible use in MR imaging and tracking of cells by investigating their cytotoxic behaviors.
