This unique text - described by Chicago Medicine as "a gem" -- provides a direct, stepwise approach to GI diagnosis. Each chapter displays a specific radiographic pattern, lists all possible disease entities associated with it, and helps you refine, confirm, or reject the differential diagnosis. FEATURES: "Pattern approach" features detailed chapters, each focusing on a specific abnormal radiologic appearance and the possible pathologic entities associated with it. Heavily illustrated with over 2,400 clear images obtained using the latest technology - a great aid to visual diagnosis. Coverage includes esophageal ulceration, elevation of the diaphragm, thickening of gastric fluids, filling defects of the small bowel, abdominal calcifications, anechoic liver masses, and more. NEW TO THE FOURTH EDITION: Hundreds of new images New section on MRI of the live
