ABSTRACT:
A magnetic resonance blood flow imaging method employs a field-echo technique and a gapless multi-slice acquisition technique in which a selective excitation pulse with a flip angle of less than 90 degrees is utilized and a pulse repetition time is set shorter than usual. Imaging data are acquired from multiple slices of a subject under examination while the multiple slices are shifted in sequence in position. A cross-sectional image is reconstructed for each of the multiple slices. Images obtained by performing subtractions on plural images for the same slice are gathered to thereby produce an image of blood vessels of the subject under examination which contain at least two blood vessels which run substantially in parallel and are opposite to each other in the direction of blood flow therein.
