Abstract:
1. A magnetic resonance imaging apparatus comprising an RF wave applying device for applying an RF wave to a region to be examined of a subject in a static magnetic field, a gradient magnetic field applying device for applying a gradient magnetic field for assigning position information to said region to be examined to define a selected section, and a detecting device for detecting magnetic resonance signals from protons in said selected section, for generating image data for said region to be examined based on said magnetic resonance signals detected by said detecting device, wherein said magnetic resonance imaging apparatus further comprises a control device for: said control device, in said first pulse sequence, configured to instruct to apply a first pulse of the gradient magnetic field and a second pulse of the gradient magnetic field, wherein the first pulse has the same area as the second pulse, wherein the first pulse has a first magnitude in a positive polarity and the second pulse has a second magnitude in a negative polarity, and wherein the second magnitude is different than the first magnitude, and causes said RF wave to be applied simultaneously with each pulse of said gradient magnetic field that has polarity of smaller magnitude from the first and second magnitudes.
