A MRI apparatus according to an embodiment includes processing circuitry. The processing circuitry obtains MR data acquired by implementing an IR method under a condition where a phase difference in a complex signal related to observed elements is equal to π, due to a difference in longitudinal magnetization relaxation time between the observed elements; generates phase data on the basis of the MR data; multiplies a phase angle in the phase data by 2n; unfolds the phase of phase data having the phase angle multiplied by 2n; multiplies the phase angle in the unfolded phase data by 1/(2n); generates a phase correction map used for correcting a phase with respect to the complex signal, by applying a complex conjugate to phase data having the phase angle multiplied by 1/(2n); and performs a phase correction on the MR data by using the phase correction map.
