Ultrasonography, also known as ultrasound imaging, is a safe, non-invasive diagnostic technique that uses high-frequency sound waves to create images of structures inside the body. It is commonly used in medical settings to assess organs, tissues, and blood flow, and plays an essential role in both routine examinations and more detailed investigations.
