MAGNETIC RESONANCEIMAGING APPARATUS AND MEASUREMENT METHOD THEREOF

摘要

There is provided a magnetic resonance measuring apparatus for acquiring spectral data with reduced influence of contamination signals from the outside of a volume of interest. For this, a magnetic resonance imaging apparatus according to the present invention acquires a first echo signal generated from an object based on a gradient magnetic field having one polarity generated by a gradient magnetic field generation unit, acquires a second echo signal generated from the object based on a gradient magnetic field having the other polarity, which is a polarity opposite to the one polarity, generated by the gradient magnetic field generation unit, and creates a graph indicating the state of metabolites using both of the first echo signal and the second echo signal.
