Predicting off-axis bone strength of the distal radius using high-resolution peripheral quantitative computed tomography based finite element modeling
… (FE) models generated from high-resolution peripheral quantitative computed tomography (HR-pQCT) images; however, these models are limited because they determine failure load under pure compressive loading conditions and neglect off-axis loads that occur during a fall on an outstretched …

The quantification of pregnancy-induced bone mineral mobilisation in the maternal appendicular skeleton with novel peripheral quantitative computed tomography (pQCT) techniques.
… in the maternal appendicular skeleton with novel peripheral quantitative computed tomography (pQCT) techniques. Adaptations in maternal calcium (Ca) economy occur during pregnancy to meet fetal demand and by birth a typical new-born contains 25-30g Ca. At the individual-level if Ca is mobilised it …

High-Resolution peripheral Quantitative Computed Tomography Based Finite Element Modelling of Distal Radius Strength: Assessing Effect of Heterogeneous Material Properties and Scan Site
The current standard high-resolution peripheral quantitative computed tomography (HR-pQCT) based finite element (FE) models of distal radius sections explains 66% of variance in experimental testing results on intact forearms under fall configuration testing. However, this FE model employs a …

Using finite element models under multiple loading conditions to improve the association between radius and tibia microarchitecture and prevalent osteoporotic vertebral fracture
… tibia and radius, measurable by high-resolution peripheral quantitative computed tomography (HR-pQCT) exist between individuals with a prevalent vertebral fracture and healthy controls. As fracture is a result of mechanical failure, FE models of these sites in physiologically relevant loading …

Translational studies into the effects of exercise on estimated bone strength
… 3 d/wk over 4 weeks. In study 2, the ability of peripheral quantitative computed tomography to provide very good prediction of midshaft humerus mechanical properties with good short-term precision in human subjects was demonstrated. In study 3, collegiate-level jumping (long and/or high jump) …

Quantification of bone using a 3.0 tesla clinical magnetic resonance scanner
… imaging and spectroscopy (MRI & MRS) as a quantitative tool for diagnosing bone abnormalities at multiple skeletal sites, which could be used in conjunction with routine clinical imaging.MRI and MRS are routinely used in the clinical setting for the diagnosis of various types of diseases …

The influence of two physical activity programs on bone and muscle health in youth with cerebral palsy and other neuromotor impairments.
… and youth with CP and CP-like conditions using peripheral quantitative computed tomography (pQCT) scans of the tibiae. Bone and muscle parameters, including bone mineral content (BMC), bone mineral density (both trabecular and cortical; BMD), bone size, and muscle size, were compared to age-, …

Using HR-pQCT and finite element analysis to inform clinical assessment of distal radius fractures
… (FE) modelling coupled with high-resolution peripheral quantitative computed tomography (HR-pQCT) allows for non-invasive in vivo assessment of bone density and stiffness throughout the fracture healing process, which may inform fracture healing progression and cast removal. Many fracture …

The potential role of shearing load in the development of toe tip necrosis syndrome
… Specimens were then imaged using High-Resolution Peripheral Quantitative Computed Tomography (HR-pQCT). Images were segmented, with measures of mean intensity acquired. Estimates of overall stiffness were also acquired using load-displacement curves. State statistics were used to compare local …

Forearm Loading (FAL) Study: A Recreational Gymnastics Intervention within a Physical Education Setting
… health was also measured using high-resolution peripheral quantitative computed tomography (HRpQCT) which assessed total bone area (Tt.Ar), cortical area (Ct.Ar), trabecular area (Tb.Ar), bone mineral density (Tt.BMD), cortical thickness (Ct.Th), trabecular bone volume fracture (Tb.BV/TV), …

The role of neuromuscular performance on bone strength and properties in the forearm and lower leg of children
… dominant forearm and lower leg imaged using peripheral quantitative computed tomography (pQCT) and high resolution pQCT (HR-pQCT). Bone mass, density, area and estimated strength were assessed. Muscle area was determined from the pQCT scans and grip strength measured via a handheld …
