Imaging In Pancreas Inflammation, Old Rules And New Trends


Assistant professor of department of Radiology, Isfahan university of medical sciences, Isfahan, Iran


In  1992,  the  Atlanta  classification  for   acute pancreatitis was introduced as  a universally applicable classification  system  for  the  various  manifestations  of  acute  pancreatitis .  This  system  was designed  to  facilitate  understanding  and  correlation of findings seen by gastroenterologists,  pathologists,  radiologists,  and  surgeons.  This  approach  was  to  be  particularly  useful  for  assessment  and  treatment of the various fluid collections identified  during  the  course  of  acute pancreatitis.  It  defined  acute  pancreatitis  as  an  acute  inflammatory  process  of the  pancreas  with  variable  involvement of  other  local  tissues  and  remote  organ  systems.
This  initial  Atlanta  classification system  represented  major  progress,  but advancing knowledge of the disease process, improved imaging, and ever-changing treatment options such as minimally invasive radiologic, endoscopic, and  laparoscopic  procedures  soon  rendered  some  of  the  definitions  inadequate or ambiguous , presenting a need  to  revise  and  update  the  Atlanta  classification. The revision in 2012 places major emphasis on revised on new criteria for pancreatic fluid collections and revises some of the clinical criteria and terminology.
To learn how imaging should be scheduled (or  not) for patients with acute pancreatitis
To become familiar with the imaging features and  the new terminology proposed in the revised  2012 Atlanta classification
To discuss the remaining limitations of the 2012  Atlanta Classification
The  goal  is  for  radiologists,  gastroenterologists,  surgeons,  and  pathologists  to  use the revised classifications to standardize imaging terminology to facilitate treatment planning and enable precise comparison  of  results  among  different  departments  and  institutions.
