Abstract
A magnetic resonance imaging system erases magnetization components of at least a pair of adjacent regions sandwiching a region to be examined including a predetermined portion of interest of an object to be examined, and then selectively excites the region to be examined to obtain image information based on magnetic resonance data of the region to be examined. The magnetic resonance imaging system includes a controller for changing the polarity of a gradient field, which is applied simultaneously with a .pi./2 pulse, in units of the pair of adjacent regions when the magnetization components are to be erased.
