ABSTRACT:
A magnetic resonance imaging method acquires interleaved k-space data from a common 2D region in two or more k-spaces. The k-spaces have a first coordinate axis and a second coordinate axis. The method comprises:a) sampling into a first direction along the first coordinate axis,b) applying a first compensation pulse,c) sampling into a second direction along the first coordinate axis, the second direction being opposite to the first direction, applying a second compensation pulse,d) repetitively carrying out the steps a) to d),e) reconstructig the data sampled in the first direction into a first image with first contract characteristics and data sampled in the second direction into a second image with second contrast characteristics different from the first, and,f) combining the first and second images.
