Dual energy x-ray absorptiometry for diagnosis of bone mineral density in pre and post - Menopausal women.

Abstract

Osteoporosis is a common metabolic bone disorder causing fractures and incurring substantial morbidity and mortality specially in women after menopause. Patients and Methods: The bone mineral density of (172) pre and post-menopausal women with a mean age (31.5) and (64.5) years respectively underwent dual energy x-ray absorptiometry (DEXA) during the period. (BMD) measurements and the resulting patient classification based on T- scores values according to WHO criteria. Results: (54.08%) of post- menopausal women were in the osteoporotic range specially in spine, (29.12%) of them had osteopenia, while the others were in normal (24.96%). In premenopausal women (7.48%) had osteoporosis, (14.28%) had osteopenia and (24.48 %) had normal bone mineral density according to the WHO criteria. Conclusions: This study shows lower BMD T -score for the lumbar spine and femoral neck in post - menopausal women compared with lumbar spine and femoral neck in pre-menopausal women according to the WHO criteria.
