Is it possible to perform the FFT on an MRI image to show the dominant frequency at parts of the image?

An MRI image is already an image of 2-D Fourier magnitudes of the underlying K-space data.

Hi Esuabom, You can read a bit about it here:

Look for k-space. The typical clinical image that you think of in MRI is a magnitude image, there are some uses for phase images in MRI, which you can research.

Why not just use FFT2 like usual? Go here for some demos by Steve:
