Hello and welcome to Conditional 1. My name is James Whittaker and I am an MRI Technologist from New Zealand with an interest in MRI Safety.

This episode returns our focus to radiofrequency heating and how we can quantify it using B1+RMS.

What is B1+? What does RMS mean? How can we reduce it if we need to?

Please be aware that this episode does contain potentially disturbing discussion of the recent death of Keith McAllister in New York State.

Hello and welcome to Conditional 1. My name is James Whittaker and I am an MRI Technologist from New Zealand with an interest in MRI Safety.

It's been two years since I last released an episode of Conditional 1 so welcome to what I’m optimistically calling Season 2 of ‘Conditional 1’.

This episode will focus on the time-varying radiofrequency magnetic fields (B1) and it's interactions with the human body.

What is SAR? How high can it go? What affects how hot a patient gets when they have MRI? This episode answers these questions, and more.

Join me on Conditional 1, available on Spotify, iTunes or wherever you listen to your podcasts.
