Cumulative Transfer Function for Assessment of MRI-Induced RF Heating Risk in Pediatric Patients Implanted with Bifurcated Leads

This paper develops and validates a cumulative transfer function (cTF) framework to improve RF-heating risk assessment for bifurcated cardiac leads in MRI, showing significant error reduction compared to single-branch approximations.

RF Heating of Bipolar Epicardial Implants during MRI at 0.55 T and 1.5T: Effect of Device Length and Termination Conditions

This study evaluates RF heating of bipolar epicardial leads during MRI at 0.55 T and 1.5 T, showing field strength and termination conditions affect heating patterns and safety.

Artifacts can be deceiving: The actual location of deep brain stimulation electrodes differs from the artifact seen on magnetic resonance images

This paper investigates how MRI sequence parameters and lead configuration affect the accuracy of DBS electrode localization, finding discrepancies up to 4.99 mm between the actual tip and the MRI artifact tip.
