Continuing the excellent reputation of the first edition, leading densitometry experts Sydney Lou Bonnick, MD, FACP, and Lori Ann Lewis, MRT, CDT, have updated and expanded Bone Densitometry for Technologists to reflect the latest standards and developments in the field. Here radiologic technologists, nurse practitioners, physician assistants, and dedicated densitometry technologists can find new guidelines for bone density testing, new therapies for osteoporosis, and new treatment guidelines for osteoporosis, as well as new chapters on pediatric densitometry body composition assessments, and the use of skeletal morphometry in diagnosis and fracture risk prediction. The twelve appendices have also been updated to reflect the most current information available, including contacts for densitometry equipment manufacturers and organizations, guidelines for bone density testing and CPT codes, definitions of terms, and new conversion equations. A companion CD contains the Precision Calculator Companion for automatically calculating the short-term precision and least significant change values for a facility, and the statistical confidence level for any change in BMD, all of which are indispensable in the interpretation of serial bone density studies. In addition, a new continuing education test will allow, upon successful completion, 17 hours of Category A American Society of Radiologic Technologists' credit.
Comprehensive and informative, Bone Densitometry for Technologists, Second Edition provides all of the practical knowledge needed to expertly and professionally operate any of today's sophisticated densitometry machines.
