Materials and Methods: Eighty-seven premenopausal and 18 postmenopausal Turkish women were classified into four groups according to age. Age, height, weight, menopausal status, age at menopause (in postmenopausal women), years since menopause (in postmenopausal woman), parity and total lactation period were recorded. Lumbar spine BMD (L2-L4) was measured by dual-energy X-ray absorptiometry (DEX...

Bone density is definitely a bona fide health concern! It?s directly related to the strength of your skeletal frame, which supports your entire body and allows you to move in addition to protecting your soft organs from injury. So, the lower the bone density, the more vulnerable you are to breaks and fractures (more on that later). Bone density tests [2] are administered by health care professi...

in present pet/ct scanners, pet attenuation correction is performed by relying on the information given by ct scan. in the ct-based attenuation correction methods, dual-energy technique (dect) is the most accurate approach, which has been limited due to the increasing patient dose. in this feasibility study, we have introduced a new method that can implement dual-energy technique with only a si...

background: bisphosphonates (bps) are used extensively for managing the osteoporosis. there are some controversies on atypical fractures of femur that associated with increase in cortical thickness (ct) and bps' use. in this study, the effects of alendronate consumption were studied on femoral ct as a predictor for atypical fracture.   methods: forty nine post-menopausal women aged 50-70 years ...

Luggage inspection systems play an important role in ensuring national security at airports. In this research, an effort of a new enhancement algorithm of dual-energy Xray carry-on luggage images is proposed to ensure the national security at airports. A new approach of combing High Energy and Low Energy x-ray images, de-noise it and at the end enhance the fused image with histogram specificati...

OBJECTIVE Obesity is the source of many health problems in Guadeloupe. The aim of this study was to describe the relationships between daily energy intake and expenditure, and weight status. METHODS Three consecutive daily recalls for activities and food intake were used to assess energy expenditure and energy intake in 20- to 60-year-old Guadeloupian men and women. RESULTS The absolute dai...

Aims Dual energy CT imaging enables discrimination of materials with similar attenuation coefficients. By acquiring two CT scans at different X-ray energies of the same sample, the energy dependence of the linear attenuation coefficient can be exploited to differentiate between materials. Dual energy CT has been widely used to distinguish bone from vascular contrast agents that contain elements...

1. Assessment of nutrition in patients with chronic renal failure by body composition measurement techniques may be affected by variable hydration. 2. This study aimed to derive a four-component model of body composition (consisting of fat, protein, total body water and body mineral) from a combination of dual-energy X-ray absorptiometry and total body water measured by deuterium oxide dilution...
