Gr 10 Up-Following an essay by Galen, an ancient Greek physician, the first two sections of this book discuss the means developed to look inside the human body to diagnose illness and advance medical science. The selections focus on the stethoscope, X-rays, MRI technology, and PET scans. In the third section, issues in medical imaging are explored, such as whether mammography is a reliable form of diagnosis, whether body scans are worth the radiation risks, and the impact of rising costs on the industry. The book concludes with a discussion of the future of these technologies and medicine. The style and vocabulary of the essays are difficult. Serious researchers such as advanced-placement science students will find this title useful and informative, and the pro/con section will prove particularly helpful for debates and persuasive papers.-Lynn Evarts, Sauk Prairie High School, Prairie du Sac, WI Copyright 2006 Reed Business Information.
