From: Intrinsic MRI visualizes RF lesions within minutes after MR-guided ablation
(a) IR-SSFP images depicting an RF lesion (same lesion as shown in Figure 1) at 3 time points after ablation. Images were acquired using the following parameters: TE/TR=2/6 ms, resolution = 0.9 × 0.9 × 6 mm, and TI=730-775 ms (within the range of TI yielding optimal contrast [3]). (b) Area of the necrotic core with time after ablation for the same lesion. The slope of the fitted line was not significantly different from 0.
