New polymer could enable gastrointestinal transit monitoring without ionizing radiation

Scientists have developed a new fluorine-based tracer that can be tracked using magnetic resonance imaging (MRI) to monitor how quickly food moves through the gastrointestinal tract. The new method has so far been successfully tested in rats in a preclinical study, but it could eventually help diagnose gastrointestinal motility disorders or monitor treatment response. The study was published in Advanced Healthcare Materials.
