In routine anatomic MR images, what points in k-space have the lowest amplitudes?.Secondly, the central column of k-space (k x = 0) coincides with the peak of the MR echo. First, the central row (k y = 0) is acquired with no phase-encoding gradient (and hence no destructive wave interference caused by phase-encoding steps).

There are two reasons the central area of k-space has the largest magnitude. k-space must be filled with data in a specific order.The raw data at the exact center of k-space always has a larger magnitude than any other point.The periphery of k-space provides information about the general shape and contour of the object.The center of k-space provides information about the edges and details of the imaged object.
