Least-detectable and age-related local in vivo bone remodelling assessed by time-lapse HR-pQCT. [PDF]

PLoS ONE, 2018
We previously developed an image analysis approach for the determination of local sites of bone remodelling using time-lapse in vivo HR-pQCT. The involved image filtering for removing noise was chosen rather aggressively, and also removed some effects of

Microstructural parameters of bone evaluated using HR-pQCT correlate with the DXA-derived cortical index and the trabecular bone score in a cohort of randomly selected premenopausal women. [PDF]

PLoS ONE, 2014
BackgroundAreal bone mineral density is predictive for fracture risk. Microstructural bone parameters evaluated at the appendicular skeleton by high-resolution peripheral quantitative computed tomography (HR-pQCT) display differences between healthy ...

HR-pQCT imaging in children, adolescents and young adults: Systematic review and subgroup meta-analysis of normative data.

PLoS ONE, 2019
We aimed to investigate the methodologies on image acquisition of normative data of high-resolution peripheral quantitative computed tomography (HR-pQCT) in children, adolescents and/or young adults (up to 25 years) and to determine their normative data ...

Bone imaging modality precision and agreement between DXA, pQCT, and HR-pQCT. [PDF]

JBMR Plus
Quantifying precision error for dual-energy x-ray absorptiometry (DXA), peripheral quantitative computed tomography (pQCT) and high-resolution pQCT (HR-pQCT) is crucial for monitoring longitudinal changes in body composition and musculoskeletal outcomes.

Bone mineral density and bone microarchitecture in a cohort of patients with Erdheim-Chester Disease

Orphanet Journal of Rare Diseases, 2020
Background Erdheim-Chester Disease (ECD) is a rare type of non-Langerhans histiocytosis. Skeletal structures are affected in over 95% ECD patients. Due to the lack of proper imaging assessment tools, the alteration of bone microarchitecture in ECD has ...

Coronary calcification and bone microarchitecture by high-resolution peripheral quantitative computed tomography from the São Paulo Ageing and Health (SPAH) Study

Scientific Reports, 2022
Epidemiological studies reveal a link between osteoporosis and the risk of ischemic cardiovascular disease. We illustrate an association between coronary calcification and bone microarchitecture in older adults based on the SPAH study.

Differences in the effects of BMI on bone microstructure between loaded and unloaded bones assessed by HR-pQCT in Japanese postmenopausal women

Osteoporosis and Sarcopenia, 2021
Objectives: The relationship between weight-related load and bone mineral density (BMD)/bone microstructure under normal load conditions using high-resolution peripheral quantitative computed tomography (HR-pQCT) remains unconfirmed.

What Is the Diagnostic Performance of Conventional Radiographs and Clinical Reassessment Compared With HR-pQCT Scaphoid Fracture Diagnosis? [PDF]

Clin Orthop Relat Res, 2023
BACKGROUND: Conventional radiographs and clinical reassessment are considered guides in managing clinically suspected scaphoid fractures. This is a unique study as it assessed the value of conventional radiographs and clinical reassessment in a cohort of

Vascular channels in metacarpophalangeal joints: a comparative histologic and high-resolution imaging study

Scientific Reports, 2017
We evaluated whether cortical interruptions classified as vascular channel (VC) on high-resolution peripheral quantitative computed tomography (HR-pQCT) could be confirmed by histology.
