Background And Aims: There is controversy about finding intestinal metaplasia (IM) of the gastric cardia on biopsy. The most recent American College of Gastroenterology guideline comments that IM cardia is not more common in patients with Barrett's esophagus (BE). It provides limited guidance on whether the cardia should be treated when patients with BE undergo endoscopic eradication therapy (EET) and whether the cardia should undergo biopsy after ablation.

Materials And Methods: This prospective HIPAA-compliant study was approved by the institutional review board and the institutional conflict of interest committee. All patients provided written informed consent.
Background & Aims: The use of computed tomography enterography (CTE) in patients with Crohn's disease has increased. However, there is little data available on how radiologic parameters of active disease change during treatment with infliximab and whether these changes correspond to symptoms, serum biomarkers, or endoscopic appearance.
Methods: We performed a retrospective study of patients with Crohn's disease who had undergone serial CTE imaging while receiving infliximab.
Background: Computed tomographic enterography (CTE) has been shown to have a high sensitivity and specificity for active small bowel inflammation. There are only sparse data on the effect of CTE results on Crohn's disease (CD) patient care.
Methods: We prospectively assessed 273 patients with established or suspected CD undergoing a clinically indicated CTE.
Background: Little information exists concerning the frequency and medical significance of incidental findings (IFs) in imaging research.
Methods: Medical records of research participants undergoing a research imaging examination interpreted by a radiologist during January through March 2004 were reviewed, with 3-year clinical follow-up. An expert panel reviewed all IFs generating clinical action to determine medical benefit/burden on the basis of predefined criteria.
Objective: The objective of our study was to prospectively obtain pilot data on the accuracy of MR enterography for detecting small-bowel Crohn's disease compared with CT enterography and with a clinical reference standard based on imaging, clinical information, and ileocolonoscopy.
Subjects And Methods: The study group for this blinded prospective study was composed of 33 patients with suspected active Crohn's ileal inflammation who were scheduled for clinical CT enterography and ileocolonoscopy and had consented to also undergo MR enterography. The MR enterography and CT enterography examinations were each interpreted by two radiologists with disagreements resolved by consensus.
Background: This study was conducted to determine the prevalence of penetrating disease and extraintestinal manifestations of Crohn's disease (CD) identified by computed tomography enterography (CTE). We also sought to examine the percentage of clinically significant new noninflammatory bowel disease (IBD) related findings in these patients.
Methods: We analyzed the records of 357 consecutive patients with previously diagnosed CD evaluated at our institution who underwent a CTE between August 2004 and October 2005.
