► In this informative video, we break down the key differences between the small and large bowel as seen on abdominal x-rays, an essential skill for anyone involved in diagnostic radiology. Understanding how to differentiate these two sections of the gastrointestinal tract is crucial for accurate interpretation of abdominal radiographs.

The video starts by explaining the anatomical positioning of the small bowel, which is typically located centrally within the abdomen. A distinctive feature of the small bowel is the presence of valvular markings known as valvulae conniventes, which are folds of the inner lining of the intestine. These markings are unique because they cross the entire width of the small bowel and are spaced very closely together. On an x-ray, these folds give the small bowel a characteristic 'stacked coin' appearance, a visual pattern that is important for identification.

In contrast, the large bowel, or colon, is usually located more peripherally in the abdomen. It has a different set of markings called haustra, which do not span the entire width of the bowel and are more widely spaced compared to the valvulae conniventes. This video provides visual examples to help viewers easily distinguish between these two structures on an x-ray.

By the end of this video, viewers will have a clear understanding of how to identify the small and large bowel on abdominal radiographs, enhancing their ability to diagnose conditions such as bowel obstructions, volvulus, or other gastrointestinal issues. This content is particularly useful for radiologists, medical students, and healthcare professionals working in gastroenterology and diagnostic imaging.
