Fundamentals of Radiology. 4th Edition

possible rewards and perils. Although this project is often referred to as the "holy grail of modern genetics," the authors cover the potential for significant abuses and end with a cautionary note that could well summarize the entire book: "The accumulation of genetic knowledge ... does not guarantee wisdom ... if such knowledge breeds a false sense of human mastery over genes, it can even lead to folly." These last nine chapters do an outstanding job of presenting complicated ideas to a nonscientific audience, as well as covering enough detail to satisfy those with a science background. The authors' presentation is balanced, and controversial arguments are examined from all sides. Their conclusions are reasonable from both a scientific and an ethical perspective. In addition, a convenient glossary of terms is included for easy reference, and explanations are clear and concise. I would recommend this volume for anyone interested in the policy implications of the new genetics. Despite a slow beginning, these authors do an excellent job of making the world of biotechnology available to the general reader. While their "genethic principles" and conclusions will be controversial to some, their arguments are worth reading by all. It was a pleasure to read the new, and distinctly improved, fourth edition of Squire's classic introduction to radiology. The text has always been designed to present the beginning student with the fundamentals necessary to approach radiographic and other forms of diagnostic imaging. Dr. Squire and her present co-author have vastly updated the text by interspersing cross-sectional imaging techniques throughout. This close juxtaposition of the plain roentgenograms with sopograms, computer tomograms (CT), and magnetic resonance images (MRI) (compared to the previous edition where a separate chapter on cross-sectional images was presented) greatly enhances the utility and clarity for all four techniques. The text is oriented by organ system, as in the past. Starting with imaging of the chest, the authors develop an algorithmic system for the approach of any film. As well, they describe in brief but sufficient detail the many alternative modalities available for imaging each region. They have retained the excellent diagrams and colorful schema of previous editions, which ease the learning process considerably. Chapters which discuss the heart (including an excellent section on nuclear imaging) and major vessels along with a complete and lucid description of abdominal radiography, sonography, and CT follow. Also helpful is their discussion of the indications for usage …
