Question about hip/pelvic MRIs

[TheTruckGuy]

So, I'm just a lowly EM resident. But I had a random thought pop into my mind the other day when ordering an MRI on my trauma block. If you got an erection during an MRI of the pelvis/hip area, would you get motion artifact? This is assuming you don't readjust, but only that one part moves. It's been a few years since I've studies the physics of MRI and I know it's slower than CT, but can't remember if it actually "cuts" slices like with the magnetic gradient, or it senses the slices through the gradient slowly.

Like from flaccid to erect while in the scanner and a series is acquiring?

You might see some motion artifact locally but not a ton. It wouldn’t mess up the actual area of interest.

It may be worth doing a randomized control study on.

What kind of hospital is this where the ER is asking for penis MRIs?

I saw one for penis fracture. Probably wasn't necessary but this is supposed to be man's greatest hospital.

I was on the trauma service and someone had a pretty messed up pelvis. In a hypothetical scenario it's possible to get an erection while in neurogenic shock, I believe.

So, someone could have a spontaneous erection while getting scanned.

Also, does throckmorton sign apply in advanced imaging like CT or MRI?
