Abstract
According to one embodiment, an MRI apparatus includes a data acquiring part and a data processing part. The data acquiring part acquires first and second MR signals by applying at least one IR pulse under an application condition according to a relaxation time of a fluid. The first MR signals include MR signals, having negative values, from the fluid. The second MR signals include MR signals, having positive values, from the fluid. The data processing part generates first and second image data. The first image data depict the fluid as a lower signal region than that of a tissue. The second image data depict the fluid as a higher signal region than that of the tissue. The data processing part generates the first image data with a phase correction based on the second MR signals.
