How long does an MRI take?

It can vary, and that depends on what area of the body we're looking at, and what we need to look at on that body area. So some scans may only be 10 to 20 minutes, other scans can take an hour to an hour and a half. That depends on what the doctors want us to look at, and how they want it demonstrated. So MRI scans can vary wildly in the length, but most scans are about half an hour to an hour.
