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.
The scan can take between 10 minutes to over an hour to complete. This depends on the part of the body being imaged and what type of MRI is required to show the information. Before the scan begins, the radiographer will tell you how long the scan takes, so you know what to expect.here are no after effects of the MRI itself. You will be able to carry on your day as planned once the test has been completed. If you require sedation for the scan, the MRI facility will give clear instructions on what to do before and after the scan.
