Ultrasound scan, also known as ultrasonography, “scan” (in layman terms) or a sonogram, is a medical imaging technique that uses high-frequency sound waves to produce images of the inside of the body. The sound waves bounce off different tissues, giving off echoes that are captured and turned into real-time images or videos that are viewed on a monitor screen.

Unlike x-rays, ultrasound does not use ionizing radiation to create images. This makes it a safe and non-invasive method for visualizing internal organs, tissues, and even unborn babies. Ultrasound is widely used in Radiology for routine checks, to evaluate conditions such as pain, swelling, or infections and even in emergency situations due to its cost effectiveness and easy accessibility.
