[Measurement of gastric emptying by magnetic resonance imaging].
The purpose of the study was to establish a new method of measuring gastric emptying using MR Imaging in human. Gastric emptying was measured in 6 healthy male volunteers aged from 28 to 43 years, using MR imaging and RI. The measurements were performed after the oral administration of liquid meal containing glucose, protein and fat. The MR imaging was performed with 0.5T superconducting magnet machine, and consecutive 12 transaxial T1 weighted spin echo images (TR/TE = 300/17) of the upper abdomen were recorded every 10 minutes for more than 1 hour. Gastric emptying curves and their T1/2 values obtained by MR imaging and RI method were correlated well in 5 of 6 cases. We concluded that a non invasive and radiation free method using MR imaging was proved to be a useful tool for measuring gastric emptying.
