Body Habitus Dominates Solver Choice as a Source of Uncertainty in MRI Safety Assessment of Active Implantable Medical Devices
Safa Hameed, Fuchang Jiang, Bhumi Bhusal +3
MRI is increasingly critical for patients with active implantable medical devices (AIMDs), yet access depends on safety labeling derived from computational heating predictions unde…
Weight-Guided Constraints for Body Model and Lead Selection in Pediatric CIED MRI Safety Simulations
Safa Hameed, Kaylee Henry, Fuchang Jiang +5
Pediatric patients with cardiac implantable electronic devices (CIEDs) face limited MRI access due to RF-induced heating, and computational modeling is increasingly used to charact…
Comparative Study of RF Heating in Deep Brain Stimulation Devices During MRI at 1.5 T and 0.55 T: Challenging the Assumption of Safety at Low Field Strengths
Bhumi Bhusal, Pia Panravi Sanpitak, Jasmine Vu +6
Purpose: Low-field MRI has been assumed to be implant-friendly based on limited studies. However, RF-induced heating due to an implant is a complex resonance phenomenon, highly dep…
Safety of magnetic resonance imaging in patients with retained cardiac leads
Bach T. Nguyen, Bhumi Bhusal, Amir Ali Rahsepar +7
Purpose: To evaluate safety of MRI in patients with fragmented retained leads (FRLs) through numerical simulation and phantom experiments. Methods: Electromagnetic and thermal simu…
