Imaging for acute pancreatitis
First time presentation, abdominal pain, and increased amylase and lipase with high clinical certainty of diagnosis; LESS THAN 48–72 hours after onset of symptoms; clinical score irrelevant;
unknown cause => US abdomen to assess for gall stones
Everything else, probably => CT abdomen with contrast, see below.
Critically ill, systemic inflammatory response syndrome (SIRS), severe clinical scores (eg, acute physiology and chronic health evaluation [APACHE], bedside index of severity in acute pancreatitis score (BISAPS), and/or Marshall); GREATER THAN 48–72 hours after onset of symptoms. => CT abdomen with contrast
Continued SIRS, severe clinical scores, leukocytosis, and fever; >7–21 days after onset of symptoms. => CT abdomen with contrast
Initial presentation with atypical signs and symptoms, including equivocal amylase and lipase values (possibly confounded by AKI or chronic kidney disease) and when diagnoses other than pancreatitis may be possible (bowel perforation, bowel ischemia, etc). => CT abdomen with contrast
Known necrotizing pancreatic and peripancreatic pancreatitis, significant deterioration in clinical status, including abrupt decrease in hemoglobin/hematocrit, hypotension, tachycardia, tachypnea, abrupt change in fever curve, or increase in white blood cells; time
after symptom onset irrelevant. => CT abdomen with contrast
