Playing with the spaces!!! Signal, contrast and resolution information in k-space. If we erase the middle of k-space and just reconstruct the outside data we can see where the tissue boundaries are, but the signal-to-noise ratio (SNR) is low and we have no contrast information. From the other side, by reconstructing only the data from the middle of k-space we get all the signal and contrast information, but it is very blurred. Clearly we need both parts of k-space to get a useful MR image! This image has been reconstructed by the application "2D-Fourier".
