SUMMARY

With the rapid proliferation of highly sensitive bone densitometry devices since 1995, the level of skill required to operate them and interpret their results has risen sharply and now often exceeds the formal training of many operators. In Bone Densitometry for Technologists, leading densitometry experts Sydney Lou Bonnick, MD, FACP, and Lori Ann Lewis, MRT, CDT, set out to correct this deficiency by reviewing in simple language the essentials of densitometry and its day-to-day practice. Written specifically for radiologic technologists, nurse practitioners, physician assistants, and dedicated densitometry technologists, this book provides all of the practical knowledge needed to 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. Additional chapters complete the technologist's skill-set with discussions of mechanical maintenance, radiation safety, and the terminology and conventions used in the profession. Comprehensive, informative, and highly practical, Bone Densitometry for Technologists emphasizes the role of densitometry and technologists in the diagnosis and management of osteoporosis. It provides a sound basis for a complete understanding of the often esoteric technical manuals supplied by manufacturers, and goes far beyond that understanding to permit expert operation of any approved densitometry device
