“…Further evaluation of a large number of cases is warranted to determine the correlation between the clinical outcomes of the patients with the mild forms of acute pancreatitis and the MR findings. Further, as previously shown by Martin et al (25), tissue characterization by MRI could be another discriminative factor in addition to CT assessment for predicting the prognosis or severity of acute pancreatitis.…”

Purpose:To assess the usefulness of MRI and determine which MR sequence is most effective for diagnosing the mild forms of acute pancreatitis. Materials and Methods:Forty subjects (20 normal volunteers and 20 patients with a mild form of acute pancreatitis) underwent MRI with fat-suppressed T1-weighted fast lowangle shot (FLASH), half-Fourier acquisition single-shot turbo spin-echo (HASTE), and TSE short TI inversion recovery (TSE-STIR) sequences. The 20 patients with a mild form of acute pancreatitis underwent multidetector CT (MDCT) and MRI within a 24-hour interval. We qualitatively analyzed all of the images by assessing inflammatory changes in the pancreas and peripancreatic fat. We quantitatively compared differences in pancreas-liver contrast between the control and patient groups for each MR sequence by measuring the signal intensities of the pancreas and liver.Results: TSE-STIR was the best of the four modalities for delineating peripancreatic and pancreatic inflammation (P Ͻ 0.01). TSE-STIR depicted definitive peripancreatic and pancreatic inflammation in 18 and 15 patients, respectively. MDCT depicted only three cases of peripancreatic inflammation. TSE-STIR was also produced the best the best quantitative results of the MR sequences (P ϭ 0.09). Conclusion:MRI is helpful for diagnosing the mild forms of acute pancreatitis. We recommend the use of TSE-STIR imaging as part of the routine protocol for evaluating pancreatitis.

“…Data on the accuracy of CECT in diagnosing extrapancreatic or peripancreatic fat necrosis are conflicting. Although eight groups claimed that fat necrosis could not be determined reliably by CECT92, 106, 107, several studies demonstrated a good correlation between extrapancreatic findings on CECT and the presence of fat necrosis at operation or autopsy104, 108, 109.…”

Results: A total of 447 articles was assessed, including 12 guidelines and 82 reviews. Alternative definitions of predicted severity of acute pancreatitis, actual severity and organ failure were used in more than half of the studies. There was a large variation in the interpretation of the Atlanta definitions of local complications, especially relating to the content of peripancreatic collections. Conclusion:The Atlanta definitions for acute pancreatitis are often used inappropriately, and alternative definitions are frequently applied. Such lack of consensus illustrates the need for a revision of the Atlanta Classification.
