Figure 2
Temperature at the tip of the nitinol guidewire measured during 2 minutes of continuous scanning using Cartesian bSSFP (TE/TR = 1.31/2.62 ms, flip angle = 45°) (A) and spiral gradient echo (TE/TR = 0.86/8.16 ms, flip angle = 10°) (B). Signal oscillation is observed in the non-linear range of the temperature probe (>85°C).
