- To evaluate the extent and severity of pancreatic inflammation and necrosis. (correct)
Why is it important to use thin sections during a CT scan for acute pancreatitis?
Why is it important to use thin sections during a CT scan for acute pancreatitis?
- To speed up the data acquisition process and reduce scanning time.
- To minimize the need for intravenous contrast agents.
- To reduce the overall radiation exposure to the patient.
- To improve the detection of subtle changes and abnormalities within the pancreas. (correct)

What is the purpose of administering oral water prior to a CT scan for pancreatitis?
- To opacify the stomach, duodenum, and jejunum enhancing visualization. (correct)
- To hydrate the patient and improve kidney function.
- To slow down the absorption of the intravenous contrast agent.
- To reduce artifacts caused by air in the bowel.

Study Notes
- Contrast-enhanced CT scan is the most reliable imaging modality for staging acute pancreatitis.
- Meticulous technique is required for contrast enhanced CT scans.
- Thin sections should be obtained during maximum pancreatic enhancement.
- Oral water is administered to opacify the stomach, duodenum, and jejunum.
- An IV iodinated contrast agent is administered, with a volume of 100-150 ml injected at a rate of 3 ml/s.
- Data acquisition is delayed for 30 and 70 seconds.
- The delay enables visualization of the pancreas in both the arterial and portal venous phases of enhancement.
