Bone densitometry in pediatric populations: discrepancies in the diagnosis of osteoporosis by DXA and CT.
OBJECTIVES To test the hypothesis that because of errors associated with growth and development, osteoporosis is frequently overdiagnosed in children when using dual-energy x-ray absorptiometry (DXA). This study compared bone density values obtained by DXA with those from computed tomography (CT), which is not influenced by body or skeletal size. STUDY DESIGN Vertebral bone density was measur...
متن کاملUtilization of DXA Bone Mineral Densitometry in Ontario: An Evidence-Based Analysis.
ISSUE Systematic reviews and analyses of administrative data were performed to determine the appropriate use of bone mineral density (BMD) assessments using dual energy x-ray absorptiometry (DXA), and the associated trends in wrist and hip fractures in Ontario. BACKGROUND DUAL ENERGY X-RAY ABSORPTIOMETRY BONE MINERAL DENSITY ASSESSMENT: Dual energy x-ray absorptiometry bone densitometers meas...
متن کاملBone Loss and Seasonal Variation in Serial DXA Densitometry – A Population-Based Study
Osteoporosis is a disease of increased skeleton fragility accompanied by low BMD and microarchitectural deterioration. Osteoporosis and bone fragility result in significant morbidity and medical and social costs (Dennison et al., 2005; Cummings et al., 2002). The risk of fractures is greater among women with low BMD although it explains only part of the increased fracture tendency among the eld...
متن کاملBONE DENSITOMETRY OF MENOPAUSAL WOMEN IN TEHRAN
Using a cluster sampling method, a group of menopausal women from three geographic areas in Tehran were asked to participate in the study. Demographic data was obtained using a questionnaire. Subjects were than referred to perform bone mass densitometry (BMD). The relationship between various variables (i.e. age of menarche, number of years of endogenous estrogen exposure, ... ) with minera...
متن کاملQuality control assurance in national screening programmes for cervical cancer.
The United Kingdom established a centrally controlled formal screening programme for cervical cancer in 1988. The programme has been an unprecedented success, with the incidence of cervical cancer falling by an accelerated rate of 7% a year. Underlying the success of the programme is a rigorous system of quality assurance at all levels of activity. Quality assurance assessment in performed for ...
