1. A magnetic resonance imaging apparatus comprising:
- a fluid image data acquisition unit configured to acquire plural pieces of fluid image data from an object by imaging with applying at least three inversion recovery pulses having mutually different inversion times, the plural pieces of the fluid image data corresponding to the inversion times; and
a flow velocity measuring unit configured to obtain a flow velocity of fluid based on time variation of a signal intensity depending on the inversion times at each of plural positions set in at least one of the plural pieces of the fluid image data and a distance between the plural positions.

Abstract
A magnetic resonance imaging apparatus includes a fluid image data acquisition unit and a flow velocity measuring unit. The a fluid image data acquisition unit acquires fluid image data, corresponding to mutually different inversion times, by imaging with applying at least three inversion recovery pulses having the inversion times. The flow velocity measuring unit obtains a flow velocity of fluid based on time variation of a signal intensity depending on the inversion times at each of plural positions and a distance between the plural positions.
