PROBLEM TO BE SOLVED: To provide a method to correct actual measurement data by preconditioning of a pulse sequence of ultra-high speed MRI. SOLUTION: An improved method of the magnetic resonance imaging is that, a sequence diagnostic parameter is formed by using a first shortened MRI sequence, and the sequence diagnostic parameter which has a certain relation with a particular sequence conditioning parameter is used for calculation of the feature value of the sequence conditioning parameter. A sequence of a read-out gradient pulse is altered according to the calculated feature value of the sequence conditioning parameter, and then, the altered sequence of the read-out gradient pulse is adopted in the next MRI pulse sequence and used for obtaining a diagnostic image. The above method is particularly applied to a so-called ultra-high speed MRI processing wherein echo-planar imaging (EPI) and echo-volume imaging (EVI) are included. COPYRIGHT: (C)2004,JPO&NCIPI
