← ScienceWhich risk increases in an MRI when strong radiofrequency pulses overlap?
A)Tissue heating through RF absorption✓
B)Gradient coil mechanical failures
C)Cryogen boil-off rate acceleration
D)Magnetic field homogeneity degradation
💡 Explanation
Tissue heating increases because the SAR (Specific Absorption Rate) depends on the square of the net RF pulse amplitude. Constructive Interference enhances this mechanism, depositing increased energy therefore producing greater heating rather than accelerating cryogen boil-off rates.
