Zusammenfassung

Purpose: The purpose of the study was to measure and compare T1 and T2 relaxation times of different potential oral contrast agents for MR examination of the gastrointestinal tract. Methods and Materials: The T1 and T2 values of fruit juices, cocoa, iron-desferrioxamine solution, polyethylene glycol and a commonly used Gd-based contrast material with different concentrations were determined by means of MRI methods at a clinical MR scanner operating at 1.0 Tesla. T1 maps were obtained with an inversion prepared spoiled gradient echo sequence. T2 maps were determined using the CPMG sequence. Percentage concentrati…
