Magnetic resonance imaging apparatus and method

Abstract

A magnetic resonance imaging apparatus for imaging a plurality of different slice planes having pre-pulse applying means configured to apply a pre-pulse for affecting in-plane magnetization of all slices of a measurement target, measuring means configured to make a measurement for applying one phase encode amount for one slice plane to obtain an echo signal and dispose the echo signal in a k space, and control means configured to control operations of the pre-pulse applying means and the measuring means. The control means has first control means configured to control to repeat an operation of executing the measurement once according to a predetermined order for all slice planes of the measurement target after a first pre-pulse is applied while a phase encode amount is varied in a predetermined order until all k spaces of all slices are filled, and second control means configured to control the pre-pulse applying means so that the pre-pulse is applied every time the measurement is executed at a frequency which is different from the number of the slices of the measurement target and a multiple number of the number of the slices, and the first control means sets an initial phase encode amount of each slice so as to measure a low spatial frequency area of the k space at a timing having a large effect of the pre-pulse.
