X-Ray is one of the oldest and most commonly used medical imaging techniques. It’s a quick, painless, and non-invasive test that uses a small amount of ionizing radiation to capture images of the inside of the body — particularly bones, organs, and certain soft tissues.
When X-rays pass through the body, different tissues absorb the radiation at different levels:
During an ultrasound scan, a small device called a transducer is placed on the skin after applying a special gel. This transducer emits high-frequency sound waves that travel through the body. These sound waves bounce back when they hit organs, tissues, or fluids, and the returning echoes are converted into images on a monitor.
