  • What is a double contrast barium enema (DCBE)?

    Double Contrast Barium Enema (DCBE) There are many procedures that can identify abnormalities in the colon. A double contrast barium enema uses a silver-white compound called barium to outline the colon and rectum on an x-ray. Normally, soft tissues x-ray very poorly, but the barium coating reveals a clear outline of the colon. While the double ...

  • Double-contrast barium enema - Wikipedia

    A double-contrast barium enema is a form of contrast radiography in which x-rays of the colon and rectum are taken using two forms of contrast to make the structures easier to see. A liquid containing barium (that is, a radiocontrast agent) is put into the rectum.Barium is a silver-white metallic compound that outlines the colon and rectum on an x-ray and helps show abnormalities.

    Double-contrast barium enema detected 135 (91%) of 149 polyps, with 88% of polyps under 1 cm and 96% of larger polyps detected. Thus, the double-contrast barium enema was more effective than the single-contrast examination only for detection of polyps under 1 cm. The single-contrast barium enema was more likely performed on patients in poor physical condition and in those over 70 years old ...

  • Double-Contrast Barium Enema - an overview

    Double-contrast barium enema examination is more complex and relies on a thin coating of barium on the mucosa of the colon. Bowel preparation is important for accurate studies and is similar to that used for single-contrast studies. Air (or carbon dioxide) and barium are instilled into the colon to achieve a uniform, thin mucosal coating with barium. A high-viscosity, moderately dense ...

This is congruent with our understanding that complete filling of the LAA with contrast excludes thrombus. Therefore, we considered it safe and ethical to perform TEE only in case of LA or LAA filling defects on CTA. This is supported by the fact that no strokes or TIAs
