Which non-ionizing imaging modality is commonly used in medical diagnostics?

Ultrasound is a non-ionizing imaging modality commonly used in medical diagnostics. It employs high-frequency sound waves to create images of the inside of the body. This technique is widely recognized for its safety, particularly in contexts such as prenatal imaging, where minimizing radiation exposure to both the mother and fetus is crucial. Unlike modalities such as CT scans, X-rays, and nuclear medicine, which utilize ionizing radiation to produce images, ultrasound avoids any potential risks associated with radiation exposure. This makes ultrasound a preferred choice in numerous clinical situations, especially in obstetrics, cardiology, and emergency medicine. Its ability to provide real-time imaging and facilitate dynamic assessments further enhances its utility in various diagnostic applications.
