摘 要：Biomagnetic techniques were used to measure motility in various parts of the gastrointestinal(GI) tract,particularly a new technique for detecting magnetic markers and tracers.A coil was used to enhance the signal from a magnetic tracer in the GI tract and the signal was detected using a fluxgate magnetometer or a magnetoresistor in an unshielded *** of esophageal transit time were affected by the position of the *** reproducibility of estimates derived using the new biomagnetic technique was greater than 85% and it yielded estimates similar to those obtained using *** technique is suitable for studying the effect of emotional state on GI physiology and for measuring GI transit *** biomagnetic technique can be used to evaluate digesta transit time in the esophagus,stomach and colon,peristaltic frequency and gastric emptying and is easy to use in the hospital setting.
