Sydney Lou Bonnick, MD, FACP, and Lori Ann Lewis, MRT, CDT, have updated and expanded their highly praised 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.
