Question
Ultrasound and Magnetic Resonance Imaging (MRI), are technologies used to create images of a patient's internal features. In many instances, either technology can be used when diagnosing patients. However, ultrasound is often preferred for diagnosing moving features, while MRI is often preferred for diagnosing features surrounded by air or dense bone. Based on these differences, which of the following best describes the waves used by these technologies?
A.
Ultrasound uses electromagnetic waves, while MRI uses sonar technology with sound waves.
B.
Ultrasound and MRI both use electromagnetic waves because electromagnetic waves require a medium through which to travel.
C.
Ultrasound and MRI both use sonar technology with sound waves because sound waves are not affected by a change in medium.
D.
Ultrasound uses sonar technology with sound waves, while MRI uses electromagnetic waves.
A.

The best description of the waves used by ultrasound and MRI from the provided options is:
D. Ultrasound uses sonar technology with sound waves, while MRI uses electromagnetic waves.
Ultrasound operates using high-frequency sound waves to produce images of structures within the body, making it effective for evaluating moving features. MRI, on the other hand, utilizes magnetic fields and radio waves (which are part of the electromagnetic spectrum) to generate images of internal body structures, particularly in cases where dense bone or air is present.
