I don’t think it’s heating. I think it’s PNS because my leg will periodically twitch which I can time with the pulse sequence.

I also have some small ACL reconstruction hardware in the knee which might interact and predispose that leg to moving…

I am well acquainted with high SAR abdominal scans in a 3T from my time doing scan certification in a petmr. Even though I “know” that tissue heating from high SAR is a thing, it always surprises me when my abdomen gets warm.

I used a high spec Siemens Avanto which a University owned. We used to get people complaining about PNS in the left hip and just above the bridge of the nose. It was a weird thing, and mainly happened on cardiac scans. Some found it too painful to continue with scanning.

I’ve had a little bit of PNS, but nothing that strong.

The SAR sensation of being heated from the inside is an unusual one, I’m not sure I’ve had anything else do that?
