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 کاملPeriprosthetic tibial bone mineral density changes after total knee arthroplasty
Background and purpose - Total knee arthroplasty (TKA) may cause postoperative periprosthetic bone loss due to stress shielding. Bone also adapts to mechanical alterations such as correction of malalignment. We investigated medium-term changes in bone mineral density (BMD) in tibial periprosthetic bone after TKA. Patients and methods - 86 TKA patients were prospectively measured with dual-energ...
متن کاملBone-composition imaging using coherent-scatter computed tomography: assessing bone health beyond bone mineral density.
Quantitative analysis of bone composition is necessary for the accurate diagnosis and monitoring of metabolic bone diseases. Accurate assessment of the bone mineralization state is the first requirement for a comprehensive analysis. In diagnostic imaging, x-ray coherent scatter depends upon the molecular structure of tissues. Coherent-scatter computed tomography (CSCT) exploits this feature to ...
متن کاملComputed Tomography Evaluation of Petrous Bone Fractures
DISCLOSURES: The authors declare neither financial support, sponsorship nor conflict of interest. ABSTRACT Background: Petrous bone trauma is the sequel of blunt head injury and can have life threatening complications resulting in immediate mortality. Early detection and good knowledge of the Computed Tomography (CT) findings ensure prompt treatment of both fractures and complications. Objectiv...
متن کاملLimitations of peripheral quantitative computed tomography metaphyseal bone density measurements.
CONTEXT Peripheral quantitative computed tomography (pQCT) measurements are frequently obtained to assess cancellous bone density in the appendicular skeleton. Large variations in bone morphology associated with skeletal development may limit the interpretation of pediatric pQCT studies based on a single slice. OBJECTIVE The objective of the study was to characterize the variability in trabec...
