Hybrid Referenceless and Multibaseline PRF-Shift MR Thermometry
Stanford Reference:
09-379
Abstract
Researchers at Stanford University have developed a more accurate method for estimating temperatures in the heart during thermal therapies such as cardiac ablation. This new method is a hybrid, combining the strengths of referenceless and multi-baseline thermometry to subtract the effects of heart motion and respiration while providing a temperature estimate with a low margin of error.
Applications
Medical monitoring
- used to monitor thermal therapies, such as ablation, during cardiac procedures
Advantages
Greater accuracy
- estimates temperature with much lower error than techniques based on multi-baseline subtraction or referenceless methods alone
Simple
- requires no gating navigator acquisitions or susceptibility modeling

Stage of Research
The innovators have demonstrated that this method estimates temperature with much lower error in the left ventricular myocardium of a volunteer, compared to multi-baseline subtraction and referenceless methods alone.
