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…
Pressure dependent magnetic properties on bulk CrBr3 single crystals
Rubyann Olmos, Shamsul Alam, Po Hao Chang +6
The van der Waals class of materials offer an approach to two-dimensional magnetism as their spin fluctuations can be tuned upon exfoliation of layers. Moreover, it has recently be…
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…
