Abstract

An MRI method and apparatus perform a 3D dual echo magnetic resonance scan to acquire two sets of k-space data corresponding to the two echoes, respectively. A 2D CAIPIRINHA undersampling method as applied to the two sets of k-space data to extract two sets of sampling data, which are used to reconstruct two initial magnetic resonance images from which a final magnetic resonance image is synthesized. Because staggering is carried out in the PE or SL direction when the 2D CAIPIRINHA undersampling method is applied to the 3D scan sequence, aliasing in parallel imaging is controlled, so a greater area in the center of the field of view is undisturbed by aliasing. Coil sensitivity also is increased, enabling further acceleration. 2D CAIPIRINHA undersampling method generally uses a small acceleration factor, thereby ensuring a high signal to noise ratio.
