Abstract
According to one embodiment, a magnetic resonance imaging apparatus includes a data acquiring part and a processing circuit. The data acquiring part is configured to acquire a magnetic resonance signal after applying an inversion recovery pulse or a saturation pulse. The processing circuit generates magnetic resonance examination data based on the magnetic resonance signal, by data processing including processing for compensating an incomplete inversion of a longitudinal magnetization resulting from an inversion efficiency of the inversion recovery pulse or processing for compensating an incomplete saturation of a longitudinal magnetization resulting from a saturation efficiency of the saturation pulse.
