Conditional 1 is the MRI Safety podcast created for MRI Technologists and those with an interest in MRI Safety. Designed to stimulate discussion, Conditional 1 is produced by James Whittaker and aims to form an occasional series covering all aspects of the field of MRI Safety.
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. Conditional 1 is now available on Youtube, ...

What's the Frequency, Kenneth?
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 h...

Talking the Torque
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 exposure to the static magnetic field such as vertigo and the magneto-hydromagnetic effect. Join me on Conditio...

Lost in Translation
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 on the static magnetic field (B0) and the static magnetic field gradient (dB/dx) and their ...

In Your Eyes
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 things. First, I’ll give a brief overview of the relevant anatomy of the eye, and it’s associated...

Safety? Check! (Part One)
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. That being the case I would like to ask for your help. Do you have any funny safety check...

The Colombini Incident
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 in how we approach MRI safety. I am of course, talking about the tragic death of Michael Colombini, a 6 ye...
