Research assesses RF-induced temperature rise at 3T in four subjects, indicating MR thermometry's potential for validating thermal simulations.
Key Points
Temperature rises up to 1.9 °C were observed around the knee during RF heating scans, indicating notable heating effects.
Measured distributions of temperature rise closely matched those predicted by subject-specific simulations, with an underestimation bias.
The method employed used a PRFS approach to measure RF-induced heating, ensuring accurate separation of temperature increases from field drifts.
Findings suggest that MRT measurements are feasible within RF safety SAR guidelines, highlighting the methodology's significance for future thermal simulations.
