In a CT scan at the level of celiac trunk, following structures will be seen – a) Pancreasb) Gall bladderc) Inferior vena cavad) Duodenume) Portal vein
## **Core Concept**
The celiac trunk arises from the abdominal aorta at the level of T12/L1 vertebrae. At this level, several key abdominal structures can be visualized, including organs and major vessels that are derived from or related to the foregut.
## **Why the Correct Answer is Right**
The correct answer includes structures that are anatomically located near the level of the celiac trunk.
- **Pancreas (a)**: The pancreas is located in the retroperitoneum and its body and tail can be seen at the level of the celiac trunk.
- **Inferior vena cava (c)**: The inferior vena cava (IVC) is a major vein that runs parallel to the aorta and can be seen at this level.
- **Portal vein (e)**: The portal vein is formed by the confluence of the superior mesenteric vein and the splenic vein, usually seen around this level.
## **Why Each Wrong Option is Incorrect**
- **Option B: Gall bladder (b)**: The gallbladder is located under the liver, usually more caudally and to the right, not typically seen at the level of the celiac trunk.
- **Option D: Duodenum (d)**: While parts of the duodenum are at this level, the question seems to focus on structures consistently seen in a typical cross-section at the celiac trunk level. The duodenum's position can vary.
## **Clinical Pearl / High-Yield Fact**
A key point to remember is that the celiac trunk gives rise to the left gastric, common hepatic, and splenic arteries. Structures seen at this level are critical for diagnosing conditions like pancreatic tumors or liver disease.
## **Correct Answer:** C. a, c, e.
