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

Publications



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.
