Other Types of Medical Imaging

For certain types of clinical cases, imaging techniques can be used that do not require the use of ionizing radiation. For example, high-frequency sound waves are used in Ultrasound scans. In magnetic resonance imaging (MRI), radio waves are used together with strong magnetic fields.

Ultrasound, sometimes known as sonography, is used to view soft tissues such as muscles, internal organs and blood flow especially in real-time, while MRI delivers excellent soft tissue contrast with high resolution.

    Ultrasound Imaging

    In Ultrasound imaging, computerized images are produced by sound waves reflected by organs and other interior body parts in real-time.
