← ScienceWhich risk profoundly increases around MRI machines when radiofrequency (RF) shielding degrades from prolonged use?
A)Wave interference patterns increasing distortion
B)Quench risk due to external fields
C)Increased static electrical charge buildup
D)Induced eddy currents within conductive implants✓
💡 Explanation
When RF shielding fails, induced eddy currents in metallic implants generates heat via resistance heating; because the shielding no longer diverts the electromagnetic energy, more energy deposits in the patient. Therefore, heating risks become critical rather than acoustic noise or image distortion.
