Using ultrasound in certain medical situations offers the key advantage of not involving ionizing radiation. This characteristic is particularly significant when considering the safety of patients, as ionizing radiation can pose health risks, especially in vulnerable populations such as pregnant women and young children. Ultrasound utilizes sound waves to create images of the body's internal structures, making it a safer alternative for monitoring and diagnosing conditions without the associated risks of radiation exposure.

While other factors like cost and technician training can influence the choice of imaging modality, the avoidance of ionizing radiation remains a primary compelling reason for opting for ultrasound in specific scenarios. High-contrast images are not a distinct advantage of ultrasound compared to X-rays; in fact, X-rays typically provide better image contrast for certain types of tissues, such as bones.
