Comments on “Experimental Evaluation of Relationship Between Radiofrequency Heating Near Implanted Conductive Devices, Scanner-Reported B 1+rms , and Transmit Power”

Key Result

Missing RF shimming parameters in the original study prevent reliable identification of the mechanism causing heating spread near implanted conductive devices during MRI.

Key Points

• This work critiques the experimental evaluation of RF heating near implanted conductive devices during MRI, particularly focusing on RF shimming parameters.
• Review of previously published study on RF heating near implanted conductive devices
• Analysis of RF shimming parameters and their impact on heating
• Discussion of likely mechanisms for spread in heating results
• Identifies lack of clarity in RF shimming parameters affecting heating outcomes
• Suggests that spread in heating results may not be relevant under standard testing procedures
• Notes that the mechanism for heating spread cannot be reliably identified due to missing experimental conditions
