Sample itemWhich modality uses a strong magnetic field and radiofrequency pulses?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
D. Magnetic resonance imaging
The defining Radiation physics principle supports Magnetic resonance imaging; it is the answer that best accounts for the finding or clinical aim described.
Option by option
A. Computed tomography
Computed tomography may be useful in another context but is not supported by this scenario.
B. Fluoroscopy
Fluoroscopy does not provide the expected imaging or dental conclusion here.
C. Plain radiography
Plain radiography is less appropriate because it does not match the stated radiation physics feature.
D. Magnetic resonance imaging (correct)
Correct. Magnetic resonance imaging is the most appropriate interpretation of the key information.
