Abstract
In order to acquire an image with enhanced contrast between a fluid portion and a stationary portion without extending the imaging time even when an IR pulse is used as an RF pre-pulse, the RF pre-pulse is applied to a region upstream of an imaging region so as to excite longitudinal magnetization of the fluid portion in a negative direction, an echo signal is measured from the imaging region, and an image with enhanced contrast of the fluid portion with respect to the stationary portion is acquired on the basis of phase information of an image reconstructed by using the echo signal.
