Novel Applications in 19F Magnetic Resonance Imaging

Project description

DEENESFRITPL

MRI contrast agents may soon be able to treat conditions in addition to diagnosing them

Magnetic resonance imaging (MRI) harnesses the body's natural magnetic properties to produce detailed images of organs and tissues. Although originally intended to be used without contrast agents, research showed that such agents enhance sensitivity and/or selectivity, improving the accuracy of diagnoses in many conditions. There are now many different contrast agents available, largely based on which tissues or structures are of interest. However, increasing evidence suggests some of these may accumulate in tissues with repeated use and a need exists for alternative solutions. NOVA-MRI is harnessing the power of smart nanoparticles and their functionalisation. It could pave the way to novel contrast agents that can carry therapeutics to a target site and facilitate controlled release and treatment.

Objective

Magnetic resonance imaging (MRI) is a leading clinical diagnostic technique that is able to provide whole body imaging, and when individual cells are imaged in living animals, it can provide new insights into the biology of cell trafficking and migration. For cells to be visualised by MRI, they generally must be labelled to enable their discrimination from surrounding tissue. The development of magnetic resonance imaging (MRI) contrast agents is therefore an active area of research, where the basis for this interest is the expansion of MRI as a high-resolution and non-invasive important preclinical and clinical imaging modality. Moreover, there are now new opportunities to developing smart materials with multifunctional abilities including MRI contrast in-built within biomaterial structures, functionalisation with targeting ligands and the carrying of a therapeutic payload. This move towards a new generation of MRI contrast reagents has also been spurred on by the mounting evidence against gadolinium-based contrast agents (GBCAs). They are currently the agents of choice and were considered historically safe and well tolerated until recently. However, they have been found to accumulate in various tissues of patients who do not have renal impairment, including bone, brain and kidneys. Furthermore, in 2015, the FDA released a new safety announcement regarding GBCAs and the risk of accumulated deposits in the brain following repeated use. Whilst GBCAs are being investigated, they can still be administered but healthcare professionals have been advised to limit the use of GBCA to situations in which contrast is deemed absolutely necessary.This has opened the door to the novelty of using perfluorocarbon (19F) being incorporated inside smart nanoparticles, which can offer unique quantitative signatures for molecular MRI with no competing background signal.
