| Outline of Final Research Achievements |
The conventional cardiac magnetic resonance (MR) examination necessitates long examination times and impedes its utility as a diagnostic tool, since few cardiac patients can tolerate long procedures. Furthermore, even in current 3T-MRI, the long examination time results in a temperature rise associated with SAR. Most commercial real-time thermometer systems cannot be used for accurate temperature monitoring during MRI because they are made of magnetic materials. We have developed a novel, direct real-time temperature measurement system for use during MRI procedures. The system consists of sensors with thermocouples using non-magnetic materials, a cable with electromagnetic shielding, and a display system. The sensors and cables of the new thermometer resulted in no artifacts on MRI. The new thermometer presented here is a very effective tool for real-time temperature measurement during MRI. Furthermore, such measurement methods will aid the development of short-term MRI sequences.
