Abstract:
1. A magnetic resonance imaging apparatus comprising: a static magnetic field generating unit that generates a static magnetic field in an imaging space in which an object to be examined is disposed; a gradient magnetic field generating unit that generates gradient magnetic fields in the imaging space; a transmission unit that irradiates the object with an RF pulse; a reception unit that receives and detects a nuclear magnetic resonance signal generated from the object; a measurement controller configured to control the operation of the gradient magnetic field generating unit, the transmission unit and the reception unit to obtain measurement of a plurality of echo signals from the object, based on a predetermined pulse sequence which causes the gradient magnetic fields to include a phase blip gradient magnetic field and a frequency encode gradient magnetic field with an inverted polar character; and an arithmetic processor configured to divide the plurality of echo signals into a first echo signal group and a second echo signal group, acquire image data from the first echo signal group and mask data from the second echo signal group, and obtain a susceptibility-emphasized image through use of the image data and the mask data.
