..We surveyed radiologists' experience of VC training, compared with barium enema, and assessed attitudes towards accreditation...

..To investigate the effect of a virtual colonoscopy (VC) computed-assisted detection (CAD) system on polyp detection by trained radiographers...

..To investigate the effect of different colour three-dimensional (3D) displays on polyp detection at virtual colonoscopy (VC)...

..To investigate performance of computed-assisted detection (CAD)-assisted radiographers interpreting computed tomography colonography (CTC) in routine practice...

..These standards are intended to guide and support radiology teams across the world by promoting methods for improving the quality of CT colonography technique and the patient experience...

..e. large polyps misclassified as medium). Caution should be exercised for polyps whose colonographic diameter is below but close to the 1-cm boundary threshold in order to avoid potential miscategorisation of advanced adenomas...

..Although 3D visualization display is commonly used for polyp detection, it should not be used for measurement...

..03. Wide-angle (140-degree) CTC can reduce both numbers of missed areas and review times. However, this may be at the expense of polyp conspicuity...

..Anti-tumor necrosis factor (TNF) therapy heals many Crohn's disease (CD) anal fistulas clinically but the rate, extent, and durability of deep tissue healing and factors influencing long-term outcome are unknown...

..Traditional barium enterography (BE) has poor sensitivity and requires significant radiation. We compared the performance of capsule endoscopy (CE) with BE in children with PJS...

..Untrained reader performance is variable but generally poor. Most missed polyps are due perceptual error rather than characterization, suggesting basic training should focus heavily on lesion detection...

..There is considerable variation in the ability to report CT colonography. Prior experience in gastrointestinal radiology is a distinct advantage. Competence cannot be assumed even after directed training via a database of 50 cases...

..Future directions for virtual colonoscopy are explored, including advances toward prepless examinations and automated interpretation...

..Although already widely disseminated, important future developments, such as prepless bowel cleansing (laxative free) and computer-aided diagnosis, may establish CT colonography as the preferred first-line, whole-colon investigation...

..New imaging modalities, such as double-balloon enteroscopy (DBE), CT enterography (CTE) or magnetic resonance enterography (MRE) now provide complementary roles to CE for these indications...

..Technicians who report more slowly are more accurate. All groups reported faster as the study period progressed...

..The objective of our study was to assess the utility of MR enterography compared with capsule endoscopy for the detection of small-bowel polyps in patients with Peutz-Jeghers syndrome (PJS)...

..The objective of our study was to investigate whether an increasing number of computer-aided detection (CAD) false-positives decreases reader sensitivity, specificity, and confidence for nonexpert readers of CT colonography (CTC)...

..The patency capsule may prevent capsule retention in high-risk patients. However data on its use in routine clinical practice is limited...

..Anti-tumor necrosis factor (TNF) therapy heals Crohn's fistulas clinically, but the rate, extent, and duration to achieve fistula track healing are unknown...

..However, there are widely conflicting performance data in relation to detection of flat neoplasia. This article describes the potential and limitations of CTC and computer-aided diagnosis in the detection of flat neoplasms...

..2 is sensitive for polyp detection, with a clinically acceptable false-positive rate. ColonCAR version 1.2 has a synergistic effect to the reviewer alone, and its standalone performance may exceed even that of experts...

..CONCLUSION: Polyp conspicuity and measurement in tagged data sets were optimized at 700 HU with bone viewing windows. At less than 300 HU, conspicuity improved with abdominal viewing windows...
