title: MR enterography with oral contrast agent composed of methylcellulose, low-dose barium sulfate, sorbitol, and lactulose: assessment of diagnostic performance, reliability, image quality, and patient tolerance.
abstract: OBJECTIVE
  The objective was to show efficiency of magnetic resonance enterography (MRE) with our previously assessed new oral contrast agent.
  
  
  METHODS
  Each bowel segments was evaluated for luminal distension, wall conspicuity, wall thickening, and hyperintensity on fat-saturated (FS) T2-weighted and contrast enhancement on postcontrast FS T1-weighted images. Also, consensus scoring results of MRE exams were compared with the gold standard tests in terms of active inflammatory bowel disease detection.
  
  
  RESULTS
  Sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of MRE for active inflammatory bowel disease detection were 62%, 98%, 80%, 96%, and 71.4%, respectively.
  
  
  CONCLUSIONS
  MRE obtained with the new mixture has a high reliability and shows good correlation with endoscopic examination±biopsy.
