Ultrasonography of the Spleen

Only a few years ago, most treatises on sonography covered all the diagnostic applications of ultrasound, de- scribing organs from the brain down to the placenta. Dr. Bruneton and his associates must be thanked for pre- senting this book devoted to the spleen. It probably offers the most complete presentation of details and the richest images available in its field. This book will thus become the ultimate reference in most libraries of books on son- ography. March 1988 F.
