Figure 1From: MR-guided cardiac radiofrequency ablation with catheter-tracked local MR lesion monitoringCatheter tip is displayed relative to multi-planar reformatted slices and a surface-rendered cardiac model (a). The catheter tip position obtained from tracking (b) and verified visually in a SSFP cine scan (c). Wall thickness and T2-signal of SVC, IVC before and 40 min after ablation (d,e).
