← ScienceWhich risk increases when an MRI machine quenches?
A)Rapid helium gas expansion✓
B)Increased RF coil damage
C)Gradient coil misalignment happens
D)Cryostat vacuum space implosion
💡 Explanation
Quenching causes rapid helium gas expansion because the sudden loss of superconductivity in the magnet results in rapid resistive heating; therefore, a dangerous overpressure risk exists, rather than coil damage or misalignment changes.
