Unique among all medical texts on the subject, this volume provides a direct, stepwise approach to the differential diagnosis of abnormal findings on gastrointestinal radiographs. Each of the book's 80 chapters shows a specific radiographic pattern...lists every disease entity it could possibly be...and helps the reader confirm, refine, or reject differential diagnoses to reach the best clinical diagnosis. Using a "pattern approach," chapters focus on specific radiologic abnormal appearances rather than disease entities and outline the typical signs, symptoms, and predisposing factors for the abnormality. This edition features hundreds of new images and a new section on MRI of the liver.
