The places that specialize in full body scans will do it for cash. I think technically you need a script for any MRI, so you may still need to speak with a doctor ar their facility first. My understanding is it's more streamlined there and will be way cheaper than any hospital. If you talk to your primary or can get a telemedicine appointment online then they might be willing to write you the script and you can go to a local MRI. I would avoid the hospital as they are 5x higher in cost than my local outpatient imaging facility.
I'm in the US. I am guessing a script is the same thing wherever you are as what is called a referral here. I will ask around. Thankyou for the idea. I will research what outpatient imaging facilities are around me. Would they use some kind of mirror system to watch this image? I can't imagine a PC could be near the MRI.
"script" is "prescription" (here in US and possibly elsewhere). Imaging techniques generally require them because medicine considers the potential harm of giving patients an inconclusive diagnosis or a conclusive diagnosis for which there's no treatment. Without a symptom to weigh against these risks, it makes some sense to consider them as not "over the counter".
But in practice I think you can show up at any imaging center and get some kind of "full body MRI" to screen for cancer or some other risk. They'll probably ask about family history and other predispositions but even if you didn't have those they'd still take your money.
I will give that a shot. A family member was a signalman for the railroad for over 40 years and got melanoma back when there was no treatment for it. Perhaps that may suffice.
