Book excerpt: Featuring 137 carefully selected cases, this atlas covers virtually every aspect of clinical cross-sectional imaging of the liver, gallbladder, biliary system and pancreas. For the vast majority of the cases, both CT and MR images are included to demonstrate the different features of each lesion. Furthermore, both typical and atypical pathologies are included to facilitate the differential diagnosis in daily clinical practice. Concise yet comprehensive,this atlas includes not only imaging features of the lesions but also the related pathologic and clinical data. It is therefore useful both as a quick guide for practicing radiologists and as a brief textbook for radiologists in training.
