Study of small intestine by barium infused through a Nasojejunal tube is called as
**Core Concept**
The small intestine is a crucial part of the gastrointestinal tract, responsible for nutrient absorption. Barium studies are a type of imaging technique used to visualize the gastrointestinal tract. A Nasojejunal tube is a medical device inserted through the nose and guided into the jejunum, the middle part of the small intestine.
**Why the Correct Answer is Right**
The correct answer is a type of barium study that involves infusing barium through a Nasojejunal tube to visualize the small intestine. This technique is particularly useful for assessing the mucosal pattern, folds, and abnormalities of the small intestine. The barium flows through the jejunum, allowing for detailed imaging of the small intestine's anatomy and any potential pathologies.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not accurately describe a barium study of the small intestine using a Nasojejunal tube. **Option B:** This option is incorrect because it refers to a different imaging modality, not a barium study. **Option D:** This option is incorrect because it is a different type of barium study that involves the colon, not the small intestine.
**Clinical Pearl / High-Yield Fact**
When performing a barium study of the small intestine, it is essential to use a Nasojejunal tube to ensure accurate visualization of the jejunum and distal ileum. This technique is particularly useful for diagnosing conditions such as Crohn's disease and celiac disease.
**Correct Answer: C. Small bowel follow-through.
