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.
Whereas, aortic contrast studies may take up to 45 minutes. Most cardiac CT studies will take 60 minutes. Assuming that you are not inside the CT scanner, prior to the actual scan, patient registration and meeting with the technologist takes approximately 30 minutes.
