What is the primary purpose of diagnostic medical sonography?

The primary purpose of diagnostic medical sonography is to create images of the body's internal structures using high-frequency sound waves. This imaging technique, commonly known as ultrasound, allows healthcare professionals to visualize organs, tissues, and blood flow in a non-invasive manner. By interpreting these images, sonographers and physicians can assess conditions, monitor fetal development during pregnancy, and guide certain medical procedures. The use of sound waves ensures a safe imaging option as it does not involve radiation, making it particularly valuable in various diagnostic applications.

The other options represent different medical techniques not related to sonography. Diagnosing conditions through chemical analysis pertains to laboratory tests and blood work, delivering medication focuses on techniques like injections or infusions, and measuring electrical activity in the heart involves electrocardiograms. Each of these methods serves distinct purposes but does not align with the fundamental goals of diagnostic medical sonography.
