Sonography, also known as ultrasound imaging, is a non-invasive diagnostic technique that uses high-frequency sound waves to create real-time images of internal organs, tissues, and blood flow. It plays a vital role in detecting abnormalities in the abdomen, pelvis, heart, and pregnancy monitoring. Sonography is widely used due to its safety, accuracy, and ability to provide quick results without radiation exposure. From evaluating organ health to guiding medical procedures, ultrasound scans are essential tools for early diagnosis and effective treatment planning.
