Ultrasonography is a medical imaging technique that uses high-frequency sound waves to create images of organs and structures inside the body. It is commonly used for monitoring pregnancies, assessing heart conditions, and guiding certain medical procedures. The images produced, known as sonograms, help healthcare professionals diagnose and treat various medical conditions. This non-invasive procedure is safe and does not involve radiation, making it a preferred choice for many patients. Ultrasonography can be performed in various settings, including hospitals and outpatient clinics, and is an essential tool in modern medicine for both diagnostic and therapeutic purposes.
