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 sonar technology with sound waves, while MRI uses electromagnetic 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 electromagnetic waves, while MRI uses sonar technology with sound waves.
