The primary use of a DEXA scan is to assess bone density. DEXA, or Dual-Energy X-ray Absorptiometry, is a specific type of imaging test that measures bone mineral density (BMD) to evaluate the strength of bones and the risk of fractures. This is particularly important for diagnosing conditions such as osteoporosis, where decreased bone density significantly increases the likelihood of fractures and related complications.

The DEXA scan employs a dual-energy X-ray system that differentiates between bone mineral content and other soft tissues, allowing for precise measurement of bone density. It is a widely accepted and standard procedure, often recommended for individuals at risk of bone loss, such as postmenopausal women or older individuals, contributing significantly to preventative healthcare measures in orthopedics and geriatrics.

In contrast, the other options relate to different aspects of musculoskeletal assessment. Evaluating skeletal muscle strength involves functional testing rather than imaging. Analyzing joint movement typically requires dynamic assessments or imaging studies like MRI, which are not focused on bone density. Visualizing soft tissue injuries is done through different imaging modalities, such as ultrasound or MRI, specifically designed for soft tissue assessment rather than bone density analysis.
