Acute pancreatitis is a physiological disease first, morphological second.
❌ Imaging Priority
Early CT ordered to assess severity, leading to underestimation of necrosis and unnecessary radiation.
❌ Morphological Severity
Severity judged by fluid collections or CTSI scores early on, ignoring the physiological state.
❌ Delayed Etiology
Waiting for cross-sectional imaging before doing basic lab work or ultrasound to find the root cause.
✅ Clinical Dominance
Early phase is managed entirely by vitals, labs, and fluid resuscitation. CT is strictly avoided unless escalating.
✅ Physiological Severity
Severity is determined solely by the presence and duration of Organ Failure (Transient vs Persistent).
✅ Staged Etiology
Immediate Ultrasound and specific lab triggers drive early etiological diagnosis.

Revised Atlanta Classification Reference
Standardized terminology is mandatory for clinical-radiology integration. Avoid legacy terms such as "phlegmon" or "pancreatic abscess".
Morphologic Types
Interstitial Edematous Pancreatitis (IEP)
Diffuse/localized enlargement due to inflammatory edema. Enhances normally on contrast CT. Minimal peripancreatic fluid.
Necrotizing Pancreatitis
Lack of parenchymal enhancement and/or presence of peripancreatic necrosis. Evaluated optimally >72h.
