By and large, that's not how it happens.
The scan is performed by technologists. It is then sent to a radiologist for an opinion. The vast majority of doctors are not able to interpret the images from an MRI scan, so the type of discourse that you see on TV programs like House is not normal.
Depending on the complexity of the scan, and whether there are any abnormalities, the scan can take a variable amount of time for the radiologist to interpret.
There are then administrative issues - the scan has to be sent. The radiologist must have time to examine it, and prepare a report. The report has to be typed, then checked and signed before being sent out. 5 days is not an unreasonable estimate for a "non-urgent" scan to ensure that all the paperwork is done appropriately. In practice, the scan result will typically be available much sooner, as the administrators like to build in lots of slack time - as what they don't want to happen is someone to go back to an appointment with their doc, and the scan result not to be ready. That said, there is potentially a backlog in terms of work to be done, as there may be a shortage of radiologists, etc.
In terms of actually interpreting the scan, an expert radiologist would normally be able to interpret a MRI of their specialist area in 5-10 minutes. I'm only a trainee, and the vast majority of MRIs would take me less than 15 minutes to go through.
Unfortunately, backlogs are a major problem - Where I work, there's currently a 10 day backlog for MRI scans to be reported. (Management decided that they would operate the MRI scanners 14 hours per day instead of 10 hours, but just expected the radiologists to do 40% more work in the same time). We're now having to send many of the MRIs off to radiology outsourcing companies because we don't have enough local staff to do them.
