Fundamental Elements for Successful Performance of CT Colonography (Virtual Colonoscopy)
There are many factors affecting the successful performance of CT colonography (CTC). Adequate colonic cleansing and distention, the optimal CT technique and interpretation with using the newest CTC software by a trained reader will help ensure high accuracy for lesion detection. Fecal and fluid tagging may improve the diagnostic accuracy and allow for reduced bowel preparation. Automated carbo...
متن کاملCT colonography (virtual colonoscopy): technique, indications and performance.
Worldwide, colorectal cancer is the third most frequent cancer occurring in both sexes. Screening programs for early detection enable detection of tumors at an earlier stage and have been shown to reduce death rate. Currently, colonoscopy is the investigation of choice for colorectal cancer screening and for investigation of patients with suspected colorectal cancer. However, colonoscopy remain...
متن کاملCT Colonography (“Virtual Colonoscopy”) for Colon Cancer Screening
Background: Computed tomographic (CT) colonography, also known as "virtual colonoscopy," is an imaging technique of the colon involving helical computed tomography and computer software to generate high-resolution 2-dimensional and 3-dimensional images of the inner surface of the colon. These images are then interpreted by a radiologist to determine the presence of several types of abnormalitie...
متن کاملDiagnostic accuracy and interobserver agreement of CT colonography (virtual colonoscopy).
BACKGROUND AND AIMS Computed tomographic (CT) colonography or virtual colonoscopy (VC) is a non-invasive imaging method proposed for screening patients with colorectal neoplasias. Our aims were to study the diagnostic accuracy and interobserver agreement of VC for correct patient identification compared with conventional colonoscopy (CC). METHODS This was a prospective study of 50 patients su...
متن کاملCT colonography versus colonoscopy for the detection of advanced neoplasia.
BACKGROUND Advanced neoplasia represents the primary target for colorectal-cancer screening and prevention. We compared the diagnostic yield from parallel computed tomographic colonography (CTC) and optical colonoscopy (OC) screening programs. METHODS We compared primary CTC screening in 3120 consecutive adults (mean [+/-SD] age, 57.0+/-7.2 years) with primary OC screening in 3163 consecutive...
