Cardiac MRI usually takes 30 to 90 minutes, depending on how many pictures are needed. The test may take less time with some newer MRI machines. The MRI machine will be located in a special room that prevents radio waves from disrupting the machine.
The staff looking after you will discuss any after affects with you, and will help you if they do occur. How long does an MRI take? 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.
