The bone age of a child indicates his/her level of biological and structural maturity better than the chronological age calculated from the date of birth. Radiography of the hand & wrist is the commonest modality used to calculate bone age. Automated methods for evaluation of hand and wrist radiographs are also being developed which reduce inter rater variability compared to manual methods. Non...

Primary angiosarcoma of bone is very rare.It occurs more commonly in middle-age and later life, with a male predominance in the ratio of 2:1. Angiosarcoma of bone has a tendency to involve the long tubular bones, and multifocal involvement is common. Here, we present a case of a 69-yr-old man in Shahid Sadooghi Hospital of Yazd in 2014 that had angiosarcoma of the left tibia. He was treated wit...

Modeling and remodeling induce significant changes of bone structure and mechanical properties with age. Therefore, it is important to gain knowledge of the processes taking place in bone over time. The rat is a widely used animal model, where much data has been accumulated on age-related changes of bone on the organ and tissue level, whereas features on the nano- and micrometer scale are much ...

Chronic glucocorticoid therapy is associated with reduced bone mineral density. In paediatric patients with congenital adrenal hyperplasia, increased levels of androgens could not only counteract this effect, but could also advance bone age, with interference in the evaluation of densitometry. We evaluate bone mineral density in paediatric patients with classic congenital adrenal hyperplasia ta...

introduction : osteoporosis is characterized by low bone density and increase in the risk of fracture. because in pregnancy and lactation there are many factors which influence bone mineral density, we sought to assess whether the accumulation of multiple pregnancies and the accompanying extended periods of lactation were a risky factor for low bone mineral density and osteoporosis. materials &...

The aim of study is to measure osteoporosis in the right foot at heel (calcaneus) by using quantitative ultrasound (QUS) technique. It was measured (SOS, BUA, BQI, T-score and Z-score). While usage DXA technique tissue thickness. Osteoporosis represents low bone mineral density (BMD). uses QUS measurements because it contains a high ratio trabecular bone. predominant diagnosis used for adults, ...
