TLDR
Polyp detection was comparable for all three preparations, although phosphosoda had significantly higher patient compliance and the least residual stool.Abstract:
OBJECTIVE. 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).SUBJECTS AND METHODS. A total of 2531 patients underwent CTC followed by colonoscopy for the American College of Radiology Imaging Network (ACRIN) National CTC Trial. Of this total, 2525 patients used one of three bowel preparations with bisacodyl tablets and stool and fluid tagging: 4 L of polyethylene glycol (PEG); 90 mL of phosphosoda; or 300 mL of magnesium citrate. Patients reported percent compliance with the bowel preparation and radiologists graded each CTC examination for the amount of residual fluid and stool on a scale from 1 (none) to 4 (nondiagnostic). Reader confidence for true-positive findings was reported on a 5-point scale: 1 (low) to 5 (high). Sensitivity and specificity for detecting polyps ≥ 6 mm and ≥ 1 cm compared with colonoscopy were calculated for each prep...read more

Advances in CT Colonography for Colorectal Cancer Screening and Diagnosis.
TL;DR: CT colonography is a validated colorectal cancer test that provides an additional minimally-invasive screening option which is likely to be preferred by some patients and must be skilled in the use of both 2D and 3D interpretation methods.

TL;DR: The accuracy of CTC varied considerably between centers and did not improve as the study progressed, suggesting that this method is not yet ready for widespread clinical application.

TL;DR: Comparing the accuracy of CT colonography in detecting histologically confirmed, large colorectal adenomas and cancers with findings on screening colonoscopy and histologic review, the reference standard shows that CT colonographic screening identified 90% of asymptomatic adults with adenoma and cancers ≥10 mm in diameter that were detected by screening colonoscope.

TL;DR: Colonoscopy was more sensitive than other tests, as currently undertaken, for detection of colonic polyps and cancers, and have important implications for diagnostic use of colon imaging tests.

TL;DR: Acute phosphate nephropathy is an underrecognized cause of acute and chronic renal failure and potential etiologic factors include inadequate hydration (while receiving OSPS), increased patient age, a history of hypertension, and concurrent use of an angiotensin-converting enzyme inhibitor or angiotENSin receptor blocker.
