Ultrasound is a safe, non-invasive imaging technique that uses sound waves to create real-time images of internal organs and tissues. Widely used for diagnostics and pregnancy monitoring, ultrasound helps detect cysts, tumors, infections, and blockages. It is radiation-free, painless, and provides accurate assessments of organs such as the liver, kidneys, and reproductive system. Common types of scans include abdominal, pelvic, breast, thyroid, and antenatal scans such as the NT Scan, Growth Scan, and Anomaly Scan.
