Radio frequency induced heating of an insulated wire during magnetic resonance imaging.

Research RF Safe Research Library Jan 1, 2016

This engineering study investigated RF-induced power deposition near straight insulated leads in an MRI context under different incident electric field profiles. Using 3-D electromagnetic simulations, the authors compared simulation-derived power deposition with implant model predictions. For the setups examined,…

Visualization of the radiofrequency lesion after pulmonary vein isolation using delayed enhancement magnetic resonance imaging fused with magnetic resonance angiography.

Research RF Safe Research Library Jan 1, 2015

This study evaluated whether fusing delayed enhancement MRI (DE-MRI) with magnetic resonance angiography (MRA) improves visualization of radiofrequency ablation lesions after pulmonary vein isolation. Eighteen atrial fibrillation ablation patients underwent both imaging approaches, and two observers scored lesion…

Visualizing radiofrequency lesions using delayed-enhancement magnetic resonance imaging in patients with atrial fibrillation: A modification of the method used by the University of Utah group.

Research RF Safe Research Library Jan 1, 2015

This feasibility study evaluated whether delayed-enhancement MRI (DE-MRI) using commercially available tools could visualize radiofrequency ablation lesions in Japanese patients with atrial fibrillation. Of 15 scans, 3 were uninterpretable due to low image quality, and lesions were visualized in 8 of the remaining 12…

Comparison of submucosal resection and radiofrequency turbinate volume reduction for inferior turbinate hypertrophy: evaluation by magnetic resonance imaging.

Research RF Safe Research Library Jan 1, 2014

This prospective randomized study compared submucosal resection (SMR) with radiofrequency turbinate volume reduction (RFTVR) in 60 patients with inferior turbinate hypertrophy. Both procedures significantly reduced turbinate volume and improved nasal obstruction symptoms and nasal inspiratory peak flow by 2 months.…
