Create **high-quality, exam-oriented content for a digital academic poster on “ACUTE PANCREATITIS – A RADIOLOGICAL APPROACH”** for **final-year MBBS students**. The poster is for a **Radiology/Imaging assessment**, so make the content significantly more focused on **radiological diagnosis, imaging findings, classification, severity assessment, and complications**, rather than general medicine. ### Target level * Final-year MBBS level * Medically accurate and academically appropriate * Easy to understand and revise * Detailed enough to impress a radiology faculty member, but concise enough to fit on a single digital poster * Use standard radiology terminology * Base the content on established concepts such as the **Revised Atlanta Classification, Balthazar CT Severity Index, and Modified CT Severity Index (MCTSI)** ### Structure the poster into these sections: 1. **Title** * Acute Pancreatitis * A Radiological Approach 2. **Definition** * Give a concise definition * Mention the basic diagnostic criteria briefly 3. **Etiology** * Gallstones * Alcohol * Hypertriglyceridemia * Drugs * ERCP * Trauma * Other important causes * Keep this section brief 4. **Pathophysiology** * Explain the process in a simple flow: Acinar injury → premature enzyme activation → autodigestion → inflammation → edema → necrosis 5. **Imaging Approach** Explain the role and indications of: * Ultrasound * Contrast-enhanced CT (CECT) * MRI/MRCP Clearly mention **what each modality is best for**. 6. **Radiological Features** Explain what acute pancreatitis looks like on: * Ultrasound * CECT * MRI Include important findings such as: * Pancreatic enlargement * Altered enhancement * Peripancreatic fat stranding * Peripancreatic fluid * Necrosis * Collections 7. **Interstitial Edematous Pancreatitis vs Necrotizing Pancreatitis** Create a concise comparison table including: * Definition * CT appearance * Enhancement * Necrosis * Associated collections 8. **Revised Atlanta Classification of Pancreatic Collections** Clearly explain: * APFC – Acute Peripancreatic Fluid Collection * ANC – Acute Necrotic Collection * Pseudocyst * WON – Walled-Off Necrosis Include the important **<4 weeks vs >4 weeks** distinction and explain the contents/wall of each collection. 9. **CT Severity Assessment** Explain: * Balthazar CT Severity Index * Modified CT Severity Index (MCTSI) Give the grading/scoring in a simple, poster-friendly format and explain what increasing scores indicate. 10. **Complications** Divide them into: * Local complications * Vascular complications * Gastrointestinal complications * Thoracic/systemic complications Include important imaging findings such as: * Pseudocyst * WON * Splenic/portal vein thrombosis * Pseudoaneurysm * Hemorrhage * Pleural effusion * Ascites 11. **Important Radiology Differentials** Briefly mention important conditions that may mimic acute pancreatitis or need differentiation on imaging. 12. **Radiology Pearls / Take-Home Messages** Give 5–7 high-yield points that a final-year MBBS student should remember for an assessment/viva. ### Formatting requirements Make the content **poster-ready**, not like a textbook chapter. * Use short headings * Use bullet points * Use concise sentences * Use flowcharts wherever appropriate * Use comparison tables where useful * Highlight important radiological terms in **bold** * Avoid unnecessary clinical management details * Avoid long paragraphs * Do not overload the poster with rare complications * Clearly distinguish **diagnosis**, **severity assessment**, and **complications** At the end, provide a suggested **visual layout of the poster**, including: * Where to place CT images * Where to place ultrasound/MRI images * Which findings should have arrows/annotations * Which sections should be visually prominent * Suggested color scheme and hierarchy The final result should look like a **professional undergraduate medical radiology poster**, not an AI-generated textbook page.
