Comparison study of different bowel preparation regimens and different fecal-tagging agents on tagging efficacy, patients' compliance, and diagnostic performance of computed tomographic colonography: preliminary study.

30 Aug 2009 PURPOSE: To compare and find the optimal combination of bowel preparation regimens and different concentrations of barium-based fecal-tagging agents on computed tomographic colonography in terms of tagging efficacy, patients' compliance, and ... Read more...

Nonlinear regression-based method for pseudoenhancement correction in CT colonography.

30 Jul 2009 In CT colonography (CTC), orally administered positive-contrast tagging agents are often used for differentiating residual bowel contents from native colonic structures. However, tagged materials can sometimes hyperattenuate observed CT numbers of ... Read more...

An anthropomorphic phantom study of computer-aided detection performance for polyp detection on CT colonography: a comparison of commercially and academically available systems.

30 Jul 2009 OBJECTIVE: The objective of our study was to compare the diagnostic performances of two commercial computer-aided detection (CAD) systems and a CAD system developed in our laboratory, which we refer to as an "academic CAD system," for polyp ... Read more...
