Evaluation of Bone Mineral Content by using Dual Energy X-ray Absorptiometry

Abstract

Dual-energy X-ray Absorptiometry (DXA) is recognized as the reference method to measure bone mineral density (BMD) with acceptable accuracy errors and good precision and reproducibility.

The World Health Organization (WHO) has established DXA as the best densitometric technique for assessing BMD and based the definitions of (osteopenia and osteoporosis ) on its results.

DXA allows accurate diagnosis of osteoporosis, estimation of fracture risk and monitoring of patients undergoing treatment. 50 adults population, 29 female, 21 male with age ranged from 20-90 years no underline disease, children and pregnant women were excluded. Information obtained from examination by Dual Energy X-ray Absorptiometry (DEXA). Data collected from sampling AP projection of Lumber spines to measure and evaluate Bone Mineral Density to make differential diagnosis in Bone Mineral Density loss (normal, Osteopenia and osteoporosis) to evaluate the finding according to the T-score value. Osteopenia are 23 patient representing 46%of total .52% female and 48%male. -osteoporosis are 9 patients representing18%of total.89%female and 11%male. -Normal Sudanese are18 representing 36%of total.50%femal,50%male.
