In contrast to conventional imaging modalities, MRI allows direct visualisation of the ablation lesion. Therefore, the use of real-time MRI to guide cardiac electrophysiology procedures may increase clinical effectiveness. An essential aspect, from a decision-making point of view, is the effect on ...
None of the three mildlly edematous lesions showed progression of HO. There was no increased uptake of [' FINaF, nor were there any clinical signs reported at these sites. In contrast to these mild lesions, all three lesions with moderate edema were followed by HO progression. In addition,...
