What are the benefits vs. risks?
- Ultrasound scanning is non-invasive (no needles or injections, in most cases) and is usually painless.
- Ultrasound is widely available and easy to use.
- Ultrasound uses no ionizing radiation, making it an ideal modality for diagnosis and monitoring of pediatric patients.
- Ultrasound provides real-time imaging, making it a good tool for guiding minimally invasive procedures such as needle biopsies or fluid drainage.
- Ultrasound images can visualize structure, movement and live function in the body’s organs and blood vessels.
- For standard diagnostic ultrasound there are no known harmful effects on humans.
