Hydrophilic Polymers Enable Gastrointestinal Transit Monitoring by Fluorine‐19 Magnetic Resonance Imaging

Advanced Healthcare Materials, EarlyView.
Hydrophilic fluorinated copolymers dissolve in chyme and give a strong, single 19F signal, unlike phase‐separating perfluorocarbons. Combined 1H‐19F MRI tracks their whole‐gut transit non‐invasively and without ionizing radiation. In rats, the tracers move through the gastrointestinal tract, resist resorption, and are well tolerated, a proof‐of‐concept
