The American College of Radiology recently published the appropriateness criteria for initial imaging assessment of chronic pancreatitis (CP) and acute inflammation superimposed on CP (ACP). These criteria systematically elaborate on the role of various imaging modalities in diagnosing CP and ACP, assessing disease severity, identifying underlying causes, and evaluating complications, in order to provide guidance for effective management of CP patients through early and accurate imaging techniques and with reference to clinical and laboratory assessments. This article gives an excerpt of the key statements from the criteria.
