How does MRI operate & What to expect?


MRI images are formed by the computer processing of signals that are emitted by body tissue. These signals are generated using a safe magnetic field in combination with radio-waves of a specific frequency. Different tissue characteristics are revealed through this process and translated into different contrast levels on the image.


The procedure typically will take anywhere from 15 to 25 minutes, depending on the type of information required by your physician. All that is required of you is to be still as much as possible during the exam. In fact, some patients fall asleep during their MRI exam.
