Mayo Clinic Gastrointestinal Imaging Review PDF

Preface

The purpose of writing this book was to provide an atlas of common abnormalities that affect the gastrointestinal tract. Emphasis was placed on providing images large enough to study and minimal text including core information about the cases and disease processes. The book is not intended to be an inclusive source of diseases and their many manifestations. Rather, the most important disease processes affecting the gastrointestinal tract and their most common presentations are included. Only a few selected pediatric cases are included to provide a comparison with adult disease processes. Readers are directed to other textbooks for a comprehensive review of pediatric gastrointestinal disorders. The content of the book is directed primarily to residents in training, particularly those studying for board examinations. Practicing radiologists wanting to review the spectrum of abnormalities affecting the gastrointestinal tract will find the book to be an efficient review.

This book should be considered a new book when compared with Alimentary Tract Imaging: A Teaching File, authored by me (C.D.J.) more than a decade ago. Although some of the cases used in the earlier book also are used in this text, there are substantial differences. Additions include many new cases and also chapters on the liver, biliary system, pancreas, spleen, and mesentery and peritoneum. The book includes images obtained with state-of-theart technology, such as computed tomographic colonography and enterography, ultrasonography, and magnetic resonance (including magnetic resonance cholangiopancreatography). The format for case presentation has been standardized to description of the radiographic findings, pertinent differential diagnoses, diagnosis, and discussion. The format is designed to allow the reader to review each case without knowing the diagnosis. Students are urged to commit themselves to the findings, differential diagnoses, and then diagnosis for each case before reading the answer. They can then obtain additional information from the discussion. Numerous summary tables synthesize information and provide key points and case references. The illustrations, drawn by David A. Factor, a medical illustrator at Mayo Clinic, provide a composite of the key diseases discussed in each chapter. We hope these illustrations assist the reader in learning key differential considerations. Selected readings and references are not included—an acknowledgment that readers of this book are likely looking for an efficient single-source review.
