What is ultrasound primarily used for?

• A. Imaging the bones only
• B. Measuring blood glucose levels
• C. Producing images of internal organs and soft tissues for examination
• D. Scanning for tumors using radioactive tracer

Answer: (C)

Ultrasound uses high-frequency sound waves that travel into the body and reflect off tissues to create real-time images. This makes it especially good at visualizing soft tissues and organs—things like the liver, kidneys, pancreas, uterus, ovaries, heart, and blood vessels—along with fetal imaging during pregnancy. It’s non-invasive and does not involve ionizing radiation, so it’s safe for repeated use. While bones can create bright boundaries and gas in the intestines can obscure views, ultrasound is not limited to bones and isn’t used to measure blood glucose or to scan for tumors with radioactive tracers; those latter tasks belong to other imaging methods such as nuclear medicine. The primary use is to produce images of internal organs and soft tissues for examination.
