MRI contrast agent

Real-time MRI of a child swallowing pineapple juice whose naturally high content in paramagnetic manganese allows it to be used as an MRI contrast agent.

MRI contrast agents are contrast agents used to improve the visibility of internal body structures in magnetic resonance imaging (MRI).^[1] The most commonly used compounds for contrast enhancement are gadolinium-based contrast agents (GBCAs). Such MRI contrast agents shorten the relaxation times of nuclei within body tissues following oral or intravenous administration.
