able by EZ-EM. The day before the patient underwent CT colonography, a hydration control component was added to this preparation protocol to obtain a dry colon and to increase the homogeneity of the tagged residue. At the same time, the influence of different barium concentrations administered over the course of 1 or 2 days was evaluated.

Reader strategies for CT colonography
Abdominal Imaging, 2002Computed tomographic (CT) colonography currently faces the critical challenge of a rapidly evolving technique being validated in generalizable environments. These environments include the evaluation of the data by less expert readers who have undergone training, with standardized image display and reader protocols.

The Challenges of CT Colonography Reimbursement
Journal of the American College of Radiology, 2013CT colonography has been shown to be an effective method to screen for colorectal cancer. However, at present, full endorsement and reimbursement for screening CT colonography, particularly by the US Preventive Services Task Force and CMS, respectively, are absent, so this screening option is infrequently used, and optical colonoscopy remains the de ...

Complications of CT colonography: A Review
European Journal of Radiology, 2013Since its inception, one of the main advantages of computed tomography colonography (CTC) over colonoscopy has been its assumed superior safety profile. However CTC is not without complication and adverse events are well described. Although the risks of insufflation, bowel preparation, contrast media and radiation dose are very small, they are not ...

CT colonography: examination prerequisites
Abdominal Imaging, 2002CT colonography is likely to play an important role in colorectal cancer screening. The ability of this new technique to detect colorectal polyps and cancer is predicated on an optimally cleansed and distended colon. Whereas the most common reported colonic cleansing regimen employed for CT colonography is polyethylene glycol lavage solution, saline ...

CT colonography: pitfalls and interpretation
Abdominal Imaging, 2002A knowledge of normal colonic anatomy and its variants as demonstrated on CT colonography is essential to limit false positive results and ensure a high sensitivity for polyp detection. Interpretive and perceptual errors undoubtedly decrease with increasing operator experience.
