1. A magnetic resonance imaging apparatus comprising:
a static magnetic field generation unit configured to generate a static magnetic field in a space in which a portion to be imaged of a subject is disposed;
a measurement control unit configured to apply a gradient magnetic field and a high frequency magnetic field to the subject and to detect a nuclear magnetic resonance signal generated from the portion to be imaged; and
an arithmetic processing unit configured to reconstruct a three-dimensional image of the subject using the detected nuclear magnetic resonance signal, wherein
the arithmetic processing unit obtains a distribution of pixel values of the three-dimensional image, calculates a pixel value of a predetermined feature amount based on the distribution of the pixel values, and sets opacity for each of the pixel values included in the three-dimensional image based on the pixel value of the feature amount.
