Abstract:19F magnetic resonance imaging (19F MRI)
is gaining attention as an emerging diagnostic technology. Effective 19F MRI contrast agents (CAs) for in vivo applications require
a long transverse (or spin–spin) relaxation time (T
2), short longitudinal (or spin–lattice) relaxation
time (T
1), high fluorine content, and
excellent biocompatibility. Here, we present a novel hyperbranched
polymeric 19F MRI CA based on β-cyclodextrin and
phosphorylcholine. The influence of the branching degree and fluorine
content on T
