Updated and expanded, the Second Edition of this acclaimed text provides practical, expert guidance on the use of CT and ultrasound to diagnose acute disorders of the liver; gallbladder and bile ducts; spleen; pancreas; kidney and adrenal gland; gastrointestinal tract; pelvis; and aorta, inferior vena cava, and psoas compartments. There is an entirely new chapter on principles and techniques, and considerable new information is provided on spiral CT, MR, and color Doppler.

Each condition is fully illustrated with numerous CT and ultrasound scans.
