Computed tomographic colonography (virtual colonoscopy): a multicenter comparison with standard colonoscopy for detection of colorectal neoplasia. Acta Paediatr. Compared to CTE and MRE, ultrasound poorly demonstrates the extent of abnormalities and demonstrates poor longitudinal comparison between studies.9, Computed tomography enterography (CTE) generally demonstrates greater availability and lower initial costs compared with MRE; however, the overall cost benefit remains incompletely evaluated. Among the main advantages of this technology is absolute painlessness. Virtual colonoscopy (VC), also known as computed tomography colonography, is an effective method for detecting polyps. It is noninvasive and does not use ionizing radiation. Classic beaded appearance of the intra- and extrahepatic bile ducts can be seen in sclerosing cholangitis on MRCP (Figure 7).

Additionally, MRE is further improved with additional refinements in fat suppression such as multi-echo Dixon 3D GRE, DWI, and perfusion techniques. If polyps are found, however, an additional colonoscopy will be needed to remove them. In comparison with colonoscopy, MRE demonstrated a sensitivity of 82% and a specificity of 80% with PPV and NPV of 83% and 80% respectively. It is a stressful procedure in which a flexible tube fitted with a camera is passed into the large intestine. Then, they will give you a pair of headphones to wear during the exam.
