In Bone Densitometry for Technologists, leading densitometry experts Sydney Lou Bonnick, MD, FACP, and Lori Ann Lewis, MRT, CDT, review in simple language all the essentials of densitometry to help practicing radiologic technologists, nurse practitioners, and physician assistants expertly operate any of today's sophisticated densitometry machines. Topics range from technical descriptions of all FDA-approved densitometry devices to a clinical review of osteoporosis, and include comprehensive tutorials on computer basics, anatomy for densitometrists, the art of interpreting test results, and performing successful precision studies-all crafted to meet the daily needs of the practicing densitometrist. Comprehensive, informative, and highly practical, Bone Densitometry for Technologists is the technologist's "bible" of densitometry.
