DEXA-Scan Knochendichtemessung in Dubai

Dual-Energy X-ray Absorptiometry (DEXA) is the internationally recognised gold standard for measuring bone mineral density (BMD). The technology works by directing two X-ray beams of different energy levels through the bone being examined. Because bone and soft tissue absorb these beams differently, the scanner can precisely calculate the amount of mineral present per square centimetre of bone. This measurement, expressed in grams per square centimetre (g/cm2), is then compared to reference populations to generate T-scores and Z-scores that clinicians use for diagnosis and treatment decisions.

Osteoporosis is a systemic skeletal disease characterised by low bone mass and deterioration of bone microarchitecture, leading to increased bone fragility and fracture risk. The condition affects an estimated 200 million people worldwide and is responsible for approximately 8.9 million fractures annually. In the UAE, the prevalence of osteoporosis is significant, particularly among postmenopausal women, due to factors including vitamin D deficiency from indoor lifestyles, low calcium intake, and physical inactivity. Hip fractures carry a mortality rate of 20-30% in the first year, making early detection through DEXA scanning a potentially life-saving intervention.
