What happens to the MRI signal after it is captured and digitized?

• A. It is digitized into the viewable image
• B. It is discarded
• C. It is converted into sound
• D. It is stored as a film photograph

Answer: (A)

The main idea is that the MRI signal, once digitized, is used to create the image you see. After capture, the raw digital data from the coils are processed—typically through a Fourier transform—to reconstruct the spatial image. That reconstructed image is what is displayed on a monitor and stored as a digital file. So the digitized signal becomes the viewable image. It isn’t simply discarded, nor turned into sound, nor stored as a film photograph.
