What is an advantage of ultrasound compared to other imaging modalities?

Ultrasound is regarded as a safe imaging modality primarily because it does not utilize ionizing radiation, which distinguishes it from other imaging techniques such as X-rays or CT scans. The absence of radiation exposure is a significant advantage, particularly for certain populations such as pregnant women and children, who are more vulnerable to the potential risks associated with radiation.

In addition to safety, ultrasound is generally more accessible and less expensive than some other imaging modalities, making it a preferred choice in many clinical scenarios where real-time imaging is beneficial. Its portability allows for bedside examinations, enhancing patient care.

The attributes of ultrasound contribute to its widespread application in various medical fields, including obstetrics, cardiology, and musculoskeletal imaging, among others.
