What are the benefits and risks of ultrasound imaging?
Benefits:
Ultrasound imaging is a painless procedure. It does not use x-rays or any other type of ionizing radiation to produce an image. It is non-invasive. It can be used safely during pregnancy.
Ultrasound provides real time imaging, making it a good tool for guiding some invasive procedures such as needle biopsies.
Ultrasound can visualize movement and function and therefore can examine blood vessels and blood flow to different organs.
Risks:
For standard diagnostic ultrasound there are no known harmful effects to humans.
Ultrasound has been used for medical diagnosis for over thirty years, during which time no adverse effects have been observed.
Studies in animals and humans did not show any side effects of the use of diagnostic ultrasound.
