This educational exhibit will have the following goals: 1.  To enhance awareness of the spectrum of diseases which may affect the biliary tree. 2.  To demonstrate the utility of Minimum intensity (MinIP) views in the evaluation of a wide scpectrum of biliary diseases. 3.  To correlate MinIP views of biliary pathology with MRCP.

An introduction to MinIP reformatting will be provided.  Subsequently, a range of biliary diseases will be shown using MinIP views.  Entities to be discussed will include congenital conditions such as choledochal cysts, inflammatory processes, benign causes of biliary obstruction, and neoplastic involvement of the biliary tree, including primary and secondary tumors.  The anatomic detail provided by MinIP projection images will be illustrated, and correlation with MRCP will be made.

MinIP reformating is an under-utilized technique in depicting biliary diseases.  MinIP post-processing highlights low attenuation structures such as biliary ducts against the background of enhancing liver parenchyma, and allows for accurate depiction of a wide spectrum of biliary pathology.  In this pictorial essay, we will discuss the added value of MinIP projection images in evaluating the biliary tree on CT as well as provide MRCP correlation for MinIP views.
