Outline of Final Research Achievements |
Cardiac MRI, including that of rehabilitation patients, is a valuable non-invasive source of information on cardiac function. However, cardiac MR requires long examination times, which many rehabilitation patients cannot tolerate. Although 3T-MR was expected to facilitate shorter examination times, long examination times are still required due to the temperature rise associated with the SAR. This study describes the development of a new real-time temperature measurement device for MR, and our motivation is the expansion of short-duration MR sequences for cardiac rehabilitation patients. Our measurement system consists of non-magnetic thermocouple sensors, an electromagnetically shielded cable, and a display. The sensors and cables of the new thermometer resulted in almost no artifacts on MR images. The thermometer presented here is an effective tool for real-time temperature measurement during MR. Our measurement methods will aid the development of short-duration cardiac MR sequences.
