Sonography specifically refers to the use of ultrasound technology to create images of structures within the body. This technique employs high-frequency sound waves that are transmitted into the body, where they bounce off tissues and organs. The echoes are then captured and transformed into images, allowing for real-time visualization of various internal structures.

Sonography is widely utilized in various medical fields, including obstetrics for monitoring fetal health, cardiology for assessing heart conditions, and in many diagnostic scenarios where imaging of soft tissues is crucial. This modality is non-invasive, does not involve ionizing radiation like X-rays, and provides a dynamic view of physiological processes.

The other options involve different imaging techniques: nuclear medicine uses radioactive substances for imaging; X-rays utilize ionizing radiation; and magnetic resonance imaging (MRI) applies magnetic fields. Each of these modalities serves distinct purposes and employs different principles, underscoring that sonography is uniquely characterized by its use of ultrasound waves.
