What technique uses high-frequency sound waves to image the inside of the body?

1. MRI

2. Sonogram or echogram

3. X-ray

4. CT scan

The correct answer is: Sonogram or echogram

A Sonogram, also known as an echogram, is a medical imaging technique that uses high-frequency sound waves to produce images of the inside of the body. This technique is often used to examine organs, muscles, and tissues and is commonly used during pregnancy to monitor the growth and development of a fetus. It is a safe and non-invasive procedure that does not use radiation, making it a preferred option for many patients. Option A, MRI, uses a magnetic field and radio waves to produce detailed images of the body's internal structures. While it is also a non-invasive and radiation-free technique, MRI does not use sound waves and is a better option for visualizing soft tissues and structures like the brain and spinal cord. Option C, X-ray, uses a form of electromagnetic radiation to produce images of bones and denser tissues in the body. It is commonly used to diagnose bone
