Sonography, also called ultrasound imaging, is a non-invasive diagnostic technique that uses high-frequency sound waves to create images of organs and tissues inside the body. A device called a transducer emits sound waves that bounce off internal structures, and these echoes are converted into real-time images displayed on a monitor.
Sonography is widely used in obstetrics to monitor fetal development, in gynecology to assess the uterus and ovaries, and in many other medical fields for evaluating soft tissues, blood flow (with Doppler), and guiding biopsies. It is safe, painless, and does not involve radiation, making it especially useful for pregnant women and children.
Sonography is widely used across medicine, especially in obstetrics for monitoring fetal development, in gynecology to assess pelvic organs, and in many other fields such as cardiology, urology, and abdominal imaging. It offers the advantage of being radiation-free, painless, and relatively inexpensive, making it safe for pregnant women and children. Different types of sonography include 2D imaging, 3D and 4D imaging that provide more detailed views, and Doppler ultrasound which evaluates blood flow. Although sonography has limitations, such as difficulty imaging through bone or gas, it remains a valuable, versatile tool for diagnosis, treatment guidance, and follow-up in clinical practice.
