Full Form of DXA

What is DXA?

Dual-Energy X-ray Absorptiometry (DXA), also known as DEXA, is a medical imaging technique that measures bone mineral density (BMD). It uses two different X-ray energy levels to distinguish between bone and soft tissue, providing highly accurate readings of skeletal strength. DXA is the gold standard for diagnosing osteoporosis and assessing fracture risk. In India, DXA scans are widely used in hospitals and diagnostic centers, especially for postmenopausal women, elderly patients, and individuals with conditions like hyperparathyroidism or long-term steroid use. The procedure is quick, minimally invasive, and exposes patients to low radiation. DXA results are reported as T-scores and Z-scores, which help clinicians determine treatment plans. The test is also employed in body composition analysis to measure fat and lean mass, aiding obesity and metabolic studies. For medical students in India, understanding DXA is crucial for radiology and orthopedics exams such as NEET PG and AIIMS. The technology has become more accessible in urban and semi-urban areas, though cost and awareness remain barriers in rural regions. Overall, DXA plays a vital role in preventive healthcare by enabling early detection and management of bone diseases.
