Ultrasound in Gynecology and Obstetrics By Sam N. Hassani, M.D., (in collaboration with R.L. Bard). 182 pp., 337 illustrations, Springer-Verlag New York Inc. 1978.

In this book, Dr. Hassani has introduced to the physician a wide range of applications for diagnostic ultrasonography in the fields of obstetrics and gynecology. A large volume of material is covered in a style that provides adequate detail without verbosity. The illustra- tions are extensive, well chosen, and are predominantly of high quality gray scale images.

In each section the author attempts to present the pertinent normal regional anatomy, discuss the common diseases briefly, and correlate the sonographic findings with the histo- pathologic changes that occur. While this book is not exhaustive, the basics of ultrasound in gynecology and obstetrics are well covered.

In addition to the Ob-Gyn material, the author also provides a brief section which deals with the essential principles of ultrasound physics. Important concepts are clearly and sim- ply presented while advanced mathematics and physics are thankfully omitted. Also, some practical tips on scanning techniques are given which will be helpful to those who are not already familiar with ultrasound scanning.

This book would be of value to the obstetrician, gynecologist, radiologist, and general surgeon. The book would also be of value to the interested medical student or to the ultra- sound technician who desires to know more about the medical significance of the scans he is producing.
