Abstract: According to one embodiment, a magnetic resonance imaging apparatus includes processing circuitry. The processing circuitry estimates transmission inhomogeneity caused in a transmit RF magnetic field from a first image based on a first signal received by a whole-body coil, and estimates reception inhomogeneity caused in a receive RF magnetic field from the first image and a second image based on a second signal received by a surface coil. The processing circuitry generates a third image, having a resolution higher than a resolution of the first image and a resolution of the second image, based on a third signal received by the surface coil. The processing circuitry corrects the third image by using the estimated transmission inhomogeneity and reception inhomogeneity.

Abstract: Provided is a technique for calculating an oxygen extraction fraction by using MRI where the oxygen extraction fraction in a brain including brain parenchyma is calculated via a simple processing without an impact on an examinee, such as administration of caffeine. For this purpose, an MRI apparatus of the present invention measures a complex image of nuclear magnetic resonance signals, and calculates from thus measured complex image, a physical property distribution for obtaining a physical property image reflecting the oxygen extraction fraction. Then, thus calculated physical property distribution is separated into tissue-specific physical property distributions for at least two tissues (separated tissue images). After converting any of the separated tissue images into the oxygen extraction fraction, a distribution of the oxygen extraction fraction is estimated based on the condition that a value of any selected pixel is substantially equal to a mean value of pixels surrounding the selected pixel.
