So, digging around on the interwebs I found this:
Epidural Catheter Design | Anesthesiology | American Society of Anesthesiologists
Which says the following:
“
The catheter bodies are radiopaque; however, one manufacturer considers its catheter “magnetic-resonance-conditional” based on nonclinical testing, which allows for use under specific conditions (i.e., a static magnetic field of 3-Tesla or less, a maximum spatial gradient magnetic field of 720-Gauss/centimeter or less, and a transmit/receive radio frequency head coil).”
I took an Arrow flex-tip cath down to our 3T MRI. Holding it next to the magnet resulted in no noticeable pull. I put it against the side of the magnet and it did not stick. I then dangled the catheter in the opening of the tube, and the end did curve and pull into the tube. It was weak, not enough to feel, but there was clearly an effect. Both ends behaved similarly. I asked the tech if it would heat up if left in there long enough. She said she would expect it to heat up during a scan due to the pulsed RF. Do with that info what you will.
Now,
@pgg , where’s my money?
