Which advantage does ultrasound have over traditional imaging methods?

Ultrasound is favored in many situations due to its non-invasive nature. This characteristic allows clinicians to obtain images of various body structures without the need for incisions or invasive procedures, making it safer for patients. Being non-invasive means there is a lower risk of complications compared to methods that might require inserting instruments into the body. Additionally, patients do not need to be exposed to ionizing radiation, which is a factor in many other imaging techniques.

In contrast, options suggesting that ultrasound is always more accurate than CT scans or that it uses ionizing radiation do not represent the true capabilities and safety profile of ultrasound. Also, the statement that ultrasound can only be used on adults is incorrect; ultrasound can be utilized across all ages, including infants and children. This reflects the versatility and safety of ultrasound as an imaging modality.
