Introduction Osteoporotic bone fractures lead to weighty losses of independence and quality of life, and to increased mortality in women [1]. Minimally irradiating image techniques such as dual-energy X-ray absorptiometry (DXA) provide assessment of bone loss through the bone mineral density (BMD). Yet, fracture risk predictions remain limited with 30 to 40% of error [2]. Recently, the 3D-DXA a...

Results Analysis of four day food records following each testing session revealed average values of 1588 ± 116.7 kcal/day, 43.6 ± 7.3% protein, 35 ± 5.4% carbohydrates, 17.8 ± 7.98% fat throughout the testing period. Additionally, the participant lost 6.09 kg (13.4lb) and 2.5 BMI units. Furthermore both HHBIA (.935; p = .006) and JP7 (.954; p = 0.003) were significantly and positively correlate...

background different clinical and epidemiological studies using dual-energy x-ray absorptiometry have shown an increased prevalence of low bone mineral density in patients with inflammatory bowel diseases.the aim of this study was to assess the correlation between bone density and the disease activity in patients with ulcerative colitis. methods in this cross-sectional study, 52 patients with u...

Methods A cohort of 52 adults (aged 35.7 years, 46% men, 23 born after steroid treatment) and their term-born children (n=61, aged 8.0 years, 52% boys, 49% from a parent born after steroid treatment), was recruited in Auckland. Insulin sensitivity and secretion were assessed using hyperglycaemic clamps in adults, and HOMA-IR in children. Other assessments included DXA-derived body composition, ...

Results Females constituted 84% of the cohort with a median age at diagnosis of 13.1 years. The mean LS BMD zscores decreased with time. Initially, 9% of patients had a low BMD, this proportion increased to 19% by 3 years after diagnosis. Overall, the BMD category decreased in 35% of patients from 1 to 3rd DEXA study. LS BMD followed a general deteriorating trajectory of -0.25 z-score/year from...

Osteoporosis is known as a silent disease because bone density slowly decreases with advancing age and without symptoms. The incidence of osteoporosis is increasing yearly worldwide. Measuring bone mineral density (BMD) using conventional bone densitometry (DXA) is practical in diagnosis of osteoporosis but the cost is high and cannot be implemented in community. However, quantitative

A method to obtain 3D structural measurements of the proximal femur from 2D DXA images and a statistical atlas is presented. A statistical atlas of a proximal femur was created consisting of both 3D shape and volumetric density information and then deformably registered to 2D fan-beam DXA images. After the registration process, a series of 3D structural measurements were taken on QCT-estimates ...

Methods: We carried out measurements of bone mineral density (BMD) of lumbar spine and femoral neck using DXA, QUS of heel using ultrasound densitometer, and BMD of forearm using SXA. We performed all the measurements at the Nuclear Medicine Division of King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia between 2002 and 2004. We obtained the measurements of 437 female adult patien...

background and aim: the researches show that athletes who compete in non–weight-bearing activities، such as swimming، typically show lower bmd in the lumbar spine and lower limb sites than athletes who perform weight-bearing activities. gravitational forces produce a passive mechanical effect that plays role in developing and maintaining of bone mass. the comparison on the bone mineral density ...
