Barium Studies of the Upper Gastrointestinal Tract

In Chapter 2, a technique was described that relies primarily on barium filling and mucosal relief (i.e., single-contrast technique). The method described in this chapter relies primarily on double contrast, although it is actually a biphasic technique that combines the advantages of single and double contrast.

Multifunctional Nanosnowflakes for T1-T2 Double-Contrast …

We have fabricated the honeycomb-like MnO 2 to co-load chlorin e6 (Ce6, a photosensitizer) and ultrasmall superparamagnetic iron oxide (USPIO, T1-T2 double contrast agent). Under the high H 2 O 2 level of tumor cells, UMC efficiently degraded and triggered the exposure of photosensitizers to the generated oxygen, accelerating the …

Dots, lines, contours, and ends: An image-based review of …

On double-contrast esophagography, glycogenic acanthosis may be characterized as multiple, tiny, raised plaques which may coalesce and form a finely nodular or cobblestone mucosal pattern (Fig. 9). These lesions are most commonly seen within the mid-esophagus. This imaging appearance may overlap with esophageal candidiasis; in …

Double contrast barium enema technique

Indications. The double contrast technique is preferred over the single contrast technique when one wants a better visualization of the mucosa. In the past it had been used for colon cancer (e.g. polyp) screening 2, especially as a follow-up for failed colonoscopies, but CT colonography has effectively replaced it for that role 3.. Single …
