摘要:
To obtain an image having high ability of imaging a blood vessel in each cardiac time phase when performing imaging through a cine-PC method, an MRI apparatus includes a magnetic resonance imaging unit that collects a magnetic resonance signal; a control unit that controls the magnetic resonance imaging unit as per a pulse sequence; and a signal processing unit that prepares an image of a test target by using the magnetic resonance signal collected by the magnetic resonance imaging unit, and time phase information related to a motion of the test target. The control unit has an imaging sequence which serves as the pulse sequence, which includes applying of a flow encoding pulse, and in which an echo signal is acquired for each time phase. An applying amount of the flow encoding pulse in the imaging sequence is controlled so as to be different depending on the time phase.
