deleted_user 05/28/2013. The MRI results are actually back within an hour or two, if it is an emergency. I was rushed to the hospital on Christmas morning. The initial cat scan was done, and came back within an hour showing a possible tumor. So I was rushed to another hospital for an emergency MRI. I think the longest wait was to get on the MRI machine. I waited 6 hours. but got the results back within 4 or 5 hours. When it is a real emergency, the doctors get things done very fast. My second MRI, I asked the tech how long it takes...I was told if the doctor has hospital privileges, that he/she can look at the pictures instantaneously.
How long does a MRI take. The length of MRI examinations can vary from 15 minutes to 1 1/2 hours, averaging 45 minutes. ChaCha! [ Source: http://www.chacha.com/question/how-long-does-a-mri-take ]
