Coordination Compounds as Contrast Agents for 19F-MRI
Špánek, Jiří ; Kotek, Jan (advisor) ; Vojtíšek, Pavel (referee)
Magnetic Resonance Imaging (MRI) is one of noninvasive imaging and diagnostic methods in today's medicine. The most commonly measured nucleus is H1 of the water molecules present in the human body. There are also methods that use signal saturation transfer between the contrast agent and water molecules via exchangeable H1 nuclei, or use a different nucleus like F19 . Compounds that show a high potential in this area are complexes of paramagnetic ions such as Gd3+ , Eu3+ , Co2+ , Cu2+ and Ni2+ , which can affect relaxation times and chemical shifts of other atoms due to their magnetic properties. This Master's thesis focuses on ligands L1 and L2 which were prepared in the Bachelor thesis. The main focus is on preparation of complexes with selected paramagnetic ions and subsequent study of their properties relevant for a potential use as contrast agents for F19 -MRI and CEST methods. Keywords: F19 -MRI, CEST, macrocyclic ligands, coordination chemistry
Contrast Agents for 19F-MRI
Špánek, Jiří ; Kotek, Jan (advisor) ; Hrubý, Martin (referee)
Noninvasive imaging methods, such as MRI, are one of the most used methods in today's medicine. New MRI techniques that are being developed focus on measuring 19 F nuclei or saturation transfer between 1 H nuclei signals of contrast agent (CA) and water molecule. For these purposes, it is advantageous to use complexes of paramagnetic metal ions, whose magnetic properties cause increased rate of relaxation and thus reducing acquisition time. In this bachelor thesis two new ligands L1 and L2 are prepared, whose complexes with metal ions, such as Cu2+ and Ni2+ , could find a potencial use as CAs in methods mentioned above.
