Sonography, commonly known as ultrasound, is one of the most widely used diagnostic tools in modern medicine. It works by using high-frequency sound waves to produce clear and accurate images of internal organs, tissues, and blood vessels, all without the use of harmful radiation. Because of its safety and effectiveness, sonography is particularly important in pregnancy care, where it helps monitor the baby’s growth, development, and overall well-being throughout different stages. In addition to obstetrics, sonography plays a crucial role in diagnosing conditions related to the abdomen, pelvis, heart, thyroid, kidneys, and other vital organs. It can also detect abnormalities such as cysts, tumors, or blockages and is often used to guide minimally invasive procedures with precision. With its ability to deliver real-time imaging and accurate results, sonography has become an indispensable part of preventive health checkups and effective treatment planning.
