Fundamentals of Public Budgeting and Financeographical features of the colon. At the same time, 3D displays in and of themselves are insufficient to fully characterize a suspected polyp because CT attenuation values provide clues as to whether an area represents soft tissue or fat, or if the area contains gas as often found in foci of retained stool.

Fundamentals of Public Budgeting and Finance develop computer-aided diagnosis (CAD) of colonic polyps to address these potential obstacles to further use of CTC. In this chapter, we briefly review the progress to date and speculate on developments likely to occur during the next few years.

How Accurate Is CT Colonography? sensitivity and specificity of CTC in different patient cohorts. During this time, there have been tremendous advances in the image acquisition and display capabilities of this evolving technology. Our purpose will be to first discuss specific parameters that may affect the performance results, followed by a review of studies performed to date.

It occurred to me early on that the computer technology I used to operate a flight simulator game on my home computer might also allow me to navigate the volume of data provided by spiral CT. In other words, combining these two technologies would enable me literally to travel inside the human body.

Throughout this chapter, we will emphasize practical aspects of patient preparation that can improve both patient comfort and the quality of colonography images.
