how get k space data from MRI dicom images

Dear matlab communitee

I perform fft on dicom images and i got a complex matrix.

I need to know that is that is the k space?

I use the function fft2 to obtain it.

Is it is necessary to use hff2D?

Thank you in advance

Note, that I am by no means an expert and that this question is not even related to Matlab. However, here is my opinion:

Answer to the first question is no, if k-space refers to the Fourier transform of the MR image, because you compute the discrete Fourier transform (DFT). However, you can see the DFT as a discretized k-space.

The second question I can't answer, because hff2D is not part of my Matlab 2013b.
