CT evaluation of acute pancreatitis: 8 years clinical experience and experimental evidence.
One hundred sixty eight patients with suspected serious pancreatitis were examined by dynamic CT. According to clinical data 103 of the patients had an oedematous pancreatitis (OP) and 65 a haemorrhagic-necrotizing pancreatitis (HP). Contrast enhancement (CE) of the pancreas was measured by dynamic CT during the first 24 hours after admission to the hospital. A control study was performed in 48 hours, if the finding on the primary CT was not definite or there was a discrepancy between CT and the clinical finding. Patients with HP showed significantly lower CE during the first minute after bolus injection of contrast material than patients with either normal pancreas or those who had OP. Only 4 out of 65 patients with HP showed normal (over 40 HU) and 8 out of 103 patients with OP showed low (less than 30 HU) CE. The method seems to be the most reliable method available to differentiate HP from OP. Before giving contrast material to the patients severe hypovolemia and respiratory distress should be excluded and treated.
