摘要

To compare the efficacy and patients' tolerance of a new mixed biphasic oral contrast solution with routine biphasic oral contrast agent in magnetic resonance (MR) enterography (MRE).Thirty-seven patients (group 1) had MRE with the new mixture, whereas 14 patients (group 2) had MRE with biphasic oral contrast agent (lactulose). Magnetic resonance enterography images were evaluated by 2 experienced radiologists. Each intestinal segment was evaluated for luminal distension (LD), distinction from the surrounding tissue (wall conspicuity), and the confidence of radiologist for evaluation of the specified segment (radiological evaluation confidence). Comparisons between the 2 groups were performed using the Mann-Whitney U test. Interrater and intrarater agreement values were obtained. In addition, patients' acceptability and tolerance were assessed.The new mixture was more effective than the oral contrast agent used in group 2 for LD, wall conspicuity, and radiological confidence. The values of interrater and intrarater agreement in scoring LD, wall conspicuity, and radiological confidence were generally moderate.Our new mixture allowed good-quality enterographic images, and this solution was well tolerated by patients. In addition, this mixture is useful for evaluation of small bowels and colonic segments. We suggest the use of it for enterographic examinations.
