The worldwide consensus aims for an internationally agreed-upon classification of acute pancreatitis severity, with standardized terminology for pancreatitis and its complications.

New International Classification of Acute Pancreatitis: Many collections will remain sterile or resorb spontaneously. In addition, the RAC advocates the use of SIRS status which offers important prognostic information as increasing SIRS criteria during the initial 24 hours of hospitalization have an increased risk of persistent OF, atlata as well as mortality [ 69 ].

There is normal enhancement of the pancreatic head arrow. Necrosis can be diagnosed with MRI, which of course should only be performed if it has direct clinical implications.

Similarly Bradley and Allen [ 13 ] and Fedorak et al. Necrosis of peripancreatic tissue can be vary difficult to diagnose, but is suspected when the collection is inhomogeneous, i.
