Which application would typically NOT use sonography for imaging?

Bone densitometry is primarily performed using dual-energy X-ray absorptiometry (DXA) rather than sonography. This imaging technique is specifically designed to measure bone mineral density, which helps in assessing the risk of fractures and diagnosing conditions like osteoporosis. Unlike sonography, which uses sound waves to create images of soft tissues and organs, bone densitometry relies on X-ray technology to provide precise measurements of bone density.

In contrast, cardiac evaluations leverage echocardiography, a form of sonography, to assess heart function and structure. Obstetric imaging uses sonography extensively to visualize the developing fetus, monitor pregnancy, and evaluate maternal health. Musculoskeletal assessments also utilize sonography to examine soft tissue, ligaments, tendons, and joints for injuries or conditions. Thus, bone densitometry stands apart as the application that does not typically employ sonography for imaging.
