Abstract
A method of imaging a subject with an MRI scanner ( ) includes positioning a region of interest of the subject in the MRI scanner ( ) and executing an echo planar imaging pulse sequence therewith. A signal (S) produced by the echo planar imaging pulse sequence is received. The signal (S) includes first and second distinct sets of echos. Each echo ( ) in the first set of echos coincides with a positive polarity read gradient ( ) of the echo planar imaging pulse sequence and each echo ( ) in the second set of echos coincides with a negative polarity read gradient ( ) of the echo planar imaging pulse sequence. The method further includes collecting into a first k-space matrix data corresponding to the first set of echos and collecting into a second k-space matrix data corresponding to the second set of echos. A first image of the region of interest is reconstructed from the data in the first k-space matrix, and a second image of the region of interest is reconstructed from the data in the second k-space matrix. Preferably, the two images are temporally offset from one another, and cine or fluoroscopic imaging is achieved by alternating the frames thereof between iteratively produced first and second images.
