Medical authorities usually don't advocate for getting imagery like that as a screening tool without any relevant risk factors or symptoms. Everyone has stuff that is unique and weird about their bodies but completely benign, and chances are, it turns up in an MRI or CT. This can end up leading to unnecessary invasive procedures to remove or biopsy something. The odds (in the literal sense) are that not-called for screening leads to either worse outcomes or the same outcomes as people who didn't get the screenings.
I didn't look up a source for MRI specifically, cause that's pretty broad, but here's a report that does a good job explaining it for prostate cancer screenings. The logic is the same.

I mean, sure, but if it detects something and there's no reason to suspect it's necessarily cancerous, then I'd hope doctors would recommend just keeping an eye on it and possibly scheduling periodic checkups to ensure it doesn't continue growing. No competent doctor is going to recommend invasive surgery right off the bat.
