I had a MRI there 2 years ago and I need a copy of it for a Dr's appointment. I was told I could go to radiology and get a copy. Is it possible to get it on Sat?

Depending on what organization your other doctors office is in they may be able to get it 'pushed' over from our PACS system (the system used for Radiology images)

I don't think medical records is open on a Saturday. You may want to see if your doctor's office uses the epic system. Most digital based imaging scans are uploaded in epic for easier access in your electronic medical records file. Not 100% sure on MRI but worth a phone call
