title: Acute Pancreatitis: Revised Atlanta Classification and the Role of Cross-Sectional Imaging.
abstract: OBJECTIVE
  The 2012 revision of the Atlanta Classification emphasizes accurate characterization of collections that complicate acute pancreatitis: acute peripancreatic fluid collections, pseudocysts, acute necrotic collections, and walled-off necroses. As a result, the role of imaging in the management of acute pancreatitis has substantially increased.
  
  
  CONCLUSIONS
  This article reviews the imaging findings associated with acute pancreatitis and its complications on cross-sectional imaging and discusses the role of imaging in light of this revision.
