Clinical Imaging of Bone Microarchitecture with HR-pQCT [PDF]

Current Osteoporosis Reports, 2013
Osteoporosis, a disease characterized by loss of bone mass and structural deterioration, is currently diagnosed by dual-energy x-ray absorptiometry (DXA). However, DXA does not provide information about bone microstructure, which is a key determinant of bone strength. Recent advances in imaging permit the assessment of bone microstructure in vivo using

Microstructural abnormalities are evident by histology but not HR-pQCT at the periosteal cortex of the human tibia under CVD and T2D conditions

Medicine in Novel Technology and Devices, 2021
Cortical bone microstructure deficits may increase fracture risk in individuals with cardiovascular disease and diabetes. High resolution peripheral quantitative computed tomography (HR-pQCT) enables in vivo microstructure characterization but is limited

Assessment of trabecular and cortical parameters using high-resolution peripheral quantitative computed tomography, histomorphometry and microCT of iliac crest bone core in hemodialysis patients

Bone Reports, 2022
Patients with end-stage renal disease develop changes in bone quality and quantity, which can be assessed using different methods. This study aimed to compare and to correlate bone parameters obtained in vivo using high-resolution peripheral quantitative

The Estimation of Second-Generation HR-pQCT From First-Generation HR-pQCT Using In Vivo Cross-Calibration [PDF]

Journal of Bone and Mineral Research, 2017
ABSTRACT   Second-generation high-resolution peripheral quantitative computed tomography (HR-pQCT) provides the highest resolution in vivo to assess bone density and microarchitecture in 3D. Although strong agreement of most outcomes measured with first- (XCTI) and second- (XCTII) generation HR-pQCT ...

Bone Microarchitecture in Hemodialysis Patients Assessed by HR-pQCT [PDF]

Clinical Journal of the American Society of Nephrology, 2011
Dialysis patients are at high risk for low-trauma bone fracture. Bone density measurements using dual-energy x-ray absorptiometry (DXA) do not reliably differentiate between patients with and without fractures. The aim of this study was to identify differences in bone microarchitecture between patients with and without a history of fracture using high ...

Structural analysis of cortical porosity applied to HR-pQCT data. [PDF]

Medical physics, 2013
The investigation of cortical porosity is an important aspect of understanding biological, pathoetiological, and biomechanical processes occurring within the skeleton. With the emergence of HR-pQCT as a noninvasive tool suitable for clinical use, cortical porosity at appendicular sites can be directly visualized in vivo.
