Bone Density Measurement Using Computed Tomography
Osteoporosis is a major medical, social, and economic problem. Osteoporosis and low bone mass affect an estimated 44 million Americans (National Osteoporosis Foundation, 2008). The lifetime risk of hip, spine, or forearm fractures is estimated to be 40% in white women and 13% in white men above 50 years of age. Considerable attention is therefore focused on assessing bone mass and the ability t...
متن کاملComparison of Singh index accuracy and dual energy X-ray absorptiometry bone mineral density measurement for evaluating osteoporosis
Background: The Singh index is an inexpensive simple method to evaluate bone density, commonly used to assess osteoporosis is based on the radiological appearance of the trabecular bone structure of the proximal femur on a plain antero-posterior (AP) radiograph. The purpose of this study was to compare between Singh index and bone mineral density measurement using dual energy X-ray abs...
متن کاملMeasurement of bone density; bias and variation due to radiographic and photometric techniques.
"Bone density is an important and little-investigated variable about which we should like to know more" (American Journal of Physical Anthropology, 1954). Here an anthropologist echoed a nutritionist (Nutrition Reviews, 1952) regarding photoelectric densitometer estimates of x-ray opacity expressed as thickness of an aluminium or ivory step-wedge (or bone slabs) exposed on the same film as a li...
متن کاملSingle-site vs multisite bone density measurement for fracture prediction.
BACKGROUND Bone density measurement with dual-energy x-ray absorptiometry is widely used for fracture risk assessment. Discordance between measurement sites is common, but it is unclear how this affects fracture prediction. METHODS We performed a historical cohort study among 16 505 women 50 years or older at the time of baseline dual-energy x-ray absorptiometry of the spine and hip (mean +/-...
متن کاملBone Replacement Materials and Techniques Used for Achieving Vertical Alveolar Bone Augmentation
Alveolar bone augmentation in vertical dimension remains the holy grail of periodontal tissue engineering. Successful dental implant placement for restoration of edentulous sites depends on the quality and quantity of alveolar bone available in all spatial dimensions. There are several surgical techniques used alone or in combination with natural or synthetic graft materials to achieve vertical...
