← ScienceWhich risk increases when an MRI machine's gradient coils operate near-simultaneously at peak field?
A)Cryogen quench and magnetic field loss
B)Radiofrequency interference with nearby devices
C)Peripheral nerve stimulation in the patient✓
D)Spurious echo artifacts due to image phasing
💡 Explanation
Simultaneous action of strong gradient coils risks induced currents in the patient, because electromagnetic induction generates electrical signals, triggering peripheral nerve stimulation; therefore, careful timing is critical, rather than just field strength alone, to minimize patient discomfort.
