Conditional 1 - An MRI Safety Podcast

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 rec...

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. Keith McAllister of Long Island, New York died on the 17th July 2025 following an incident involving an MRI scanner and a heavy ferrous chain. This episode will focus on this horrifying event, what we know so far, and the potential for systemic change. Condit...

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 w...

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. With MRI Safety Week upon us once again, this episode I'm going to tell the stories of those whose loss should motivate us to do better, and talk about the lessons that should be learned from past mistakes. Join me on Conditional 1, available on Spotify,...

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 I’m going to be carrying on from Episode 5 - Lost in Translation and talking about torque and it's relationship with the static magnetic field (B0). Not only that, I'm going to discuss Lenz force and also bioeffects arising from exposur...

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 I’m going to be taking things back to basics and looking at one of the fundamentals, not just of MRI safety but MRI in general. I’m talking about the ‘M’ in MRI – magnetism. More specifically the static magnetic field.   I'm going to focus o...

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 time I’m going to be talking about an aspect of MRI Safety that has always been one of my favourites, throughout the 20+ years of my practice. I am of course, talking about Intra-orbital foreign bodies or IOFBs. In this episode I hope to achieve three th...

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. Episode 2 focuses on the safety checking of patients (and others) entering the MRI unit. Why we do it, how we do it, and when we do it. Even after splitting this into two parts it's not an exhaustive look at the process and there is always more to say.  ...

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. Episode 3 continues to focus on the safety checking of patients (and others) entering the MRI unit. Why we do it, how we do it, and when we do it. Even after splitting this into two parts it's not an exhaustive look at the process and there is always mor...

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. In this first episode "The Colombini Incident", I’m going to be talking about what is probably the single most defining moment in the history of MRI safety, to commemorate the 20th anniversary of the disastrous event that inspired a paradigm shift i...
