..The purpose of our study was to compare the effect of three different full-laxative bowel preparations on patient compliance, residual stool and fluid, reader confidence, and polyp detection at CT colonography (CTC)...

..To prospectively compare four diagnostic small-bowel imaging techniques for depiction of abnormal findings in the same patients known to have or suspected of having Crohn disease...

..The purpose of our study was to determine whether imaging changes of Crohn's disease at sequential CT enterography examinations correlate with disease progression or regression...

..Nevertheless, this new technique is easy to perform, is well tolerated by patients, and, for the first time, allows noninvasive endoscopic evaluation of the entire small bowel...

..The number of HIF can vary depending on the definition of an HIF, the patient population, as well as technical factors. This article will discuss the incidence and implication of detecting extracolonic findings at CTC...

..This article summarizes the advantages/disadvantages, scanning technique, imaging findings, performance and pitfalls of CTE for the evaluation of Crohn's disease...

..To retrospectively compare capsule endoscopic (CE) findings with findings at barium studies or computed tomography (CT) in patients without evidence of small-bowel stricture at barium examination...

..The objective of our study was to retrospectively evaluate the performance of triphasic CT enterography and identify causes of false-negative CT results in hemodynamically stable patients with suspected gastrointestinal bleeding...

..The most important issue that remains is its performance in a screening population, and studies are currently underway to answer that important question...

..To determine whether the reader's preference for a primary two-dimensional (2D) or three-dimensional (3D) computed tomographic (CT) colonographic interpretation method affects performance when using each technique...

..To compare respiratory artifacts, colonic distention, and polyp detection at computed tomographic (CT) colonography by using single- and multi-detector row helical CT systems...

....

..Larger studies are needed to better establish the role of CE for diagnosing small bowel CD in patients with a suspected initial presentation of CD...

..To determine the frequency of extracolonic findings at computed tomographic (CT) colonography and the effect of these findings on subsequent patient treatment and cost...

..The full extent of colonic disease at CTE was usually underestimated. CTE is a valid technique for detecting colitis in the colon in patients with IBD. Better methods for assessing disease activity and extent are needed...

..A systematic approach that makes use of a simple decision algorithm can help differentiate hypervascular hepatic lesions on the basis of their distinguishing MR imaging characteristics and related clinical information...

....

..Morphine administration may also be particularly helpful for the evaluation of patients with primary sclerosing cholangitis, malignant neoplasms such as cholangiocarcinoma, or cystic and non-organ-deforming benign pancreatic neoplasms...

..Imaging pitfalls that can simulate or obscure neoplasms are retained fecal material or fluid, incomplete distention, and advanced diverticulosis...

..Familiarity with the typical appearances of the normal anatomy and various pathologic conditions of the gastrointestinal tract on two- and three-dimensional cross-sectional images is useful in making the correct diagnosis...

..Familiarity with the spectrum of rectal diseases and with the potential pitfalls and technical limitations of CT colonography will help minimize interpretative and perceptual errors...

..CONCLUSION: Flat lesions of the colon represent an important source of false negative CTC examinations. Awareness of their morphology can assist radiologists in finding most of these challenging lesions...

..Early studies indicate that CTE is superior to barium examination in the evaluation of CD and is complementary to capsule endoscopy in the evaluation of OGIB...

..The purpose of this study was to determine the frequency and significance of extravascular findings on CT angiography of the abdominal aorta and lower extremities...

..The purpose of our study was to evaluate the feasibility of preserving image quality during CT colonography (CTC) using a reduced radiation dose with adaptive statistical iterative reconstruction (ASIR)...

..Computed tomographic (CT) colonography is a noninvasive option in screening for colorectal cancer. However, its accuracy as a screening tool in asymptomatic adults has not been well defined...

..The purpose of this study was to evaluate the image noise, low-contrast resolution, image quality, and spatial resolution of adaptive statistical iterative reconstruction in low-dose body CT...

..Physician awareness of the increased risk of perforation with CTC in the setting of inflammatory and/or obstructive disease of the colon will allow for improved clinical decision-making in the care of these patients...

..The aim of this study was to evaluate the diagnostic yield of CE compared with other modalities in patients with suspected and established CD using a meta-analysis...

....

..A prospective study evaluating the performance of computerized tomography colonography in a screening population is indicated...

..We sought to demonstrate that intravenous contrast-enhanced CT colonography (CTC) can distinguish colonic adenomas from carcinomas...

..Capsule retention is a rare but serious complication of capsule endoscopy (CE). The utility of routine abdominal radiographs after CE for the diagnosis of capsule retention is not established...
