Magnetic markers as a noninvasive tool to monitor gastrointestinal transit.

W Weitschies1, J Wedemeyer, R Stehr, L Trahms.   

Abstract

A novel method to monitor gastrointestinal transit of solid oral dosage forms or nutrients is presented, providing a simultaneous recording of gastrointestinal motility of the traversed section. Based on the measurement of the magnetic field of an ingested magnetized marker, its location is found by fitting a magnetic dipole field to the measured data.
