Cyclodextrins: promising scaffolds for MRI contrast agents

Autor: Géraldine Gouhier, Berthe Sandra Sembo-Backonly, François Estour

Publikováno v: RSC Advances. 11:29762-29785

Magnetic resonance imaging (MRI) is a powerful tool for non-invasive, high-resolution three-dimensional medical imaging of anatomical structures such as organs and tissues. The use of contrast agents based on gadolinium chelates started in 1988 to im
