The primary variable in the data collection procedure during MRI is the
A)repeats.
B)stationary magnet.
C)sequence of RF pulses.
D)all of the above

Question

Quizplus · Accepted Answer

The primary variable in MRI data collection is the sequence of RF (radiofrequency) pulses, which are used to excite and detect signals from the protons in the body. The stationary magnet is a constant factor in MRI imaging, and repeats may be used to improve the signal-to-noise ratio, but do not determine the primary variable in data collection. Therefore, choice C, the sequence of RF pulses, is the best answer.
