We demonstrated real time acquisition of MRI-induced heating near a simulated medical device lead (an insulated wire with exposed tip). This preliminary thermometry provided a resolution of better than 0.5 C, spatial resolution of 1.2 x 1.2 x 3 mm, and a sample rate of 3.1 sec. This is adequate for local temperature measurements near small implants per ASTM F2182 MRI safety test standard. This method has the potential to be a valuable tool for in vitro and in vivo viewing and measuring MRI-induced heating near implants in real time.
