I had an MRI done with contrast on my brain and I think the technician did the contrast wrong. He put me in the MRI without the contrast for awhile then pulled me out put the IV in and said the contrast was going in. Then he took out the IV and put me back in the MRI. I've had a CT scan with contrast before and they left the IV in the whole time. I also talked to a friend who had an MRI with contrast done and she said they left the IV in the entire time.
