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...

Dual energy virtual CT colonoscopy with dual source computed tomography: initial experience.

19 Jul 2009 PURPOSE: To describe the technique of DE MDCT colonoscopy and to assess its feasibility. MATERIALS AND METHODS: 8 patients were scanned with DSCT with a DE scan protocol and dose modulation software. Analysis was performed using dedicated DE ... Read more...
