摘要： An image processing apparatus according to an embodiment includes a processing circuitry. The processing circuitry is configured to generate a first calculated image and a second calculated image through calculation using data obtained through an imaging in which magnetic resonance signals used for deriving a tissue quantitative value are acquired, wherein a signal value of a tissue other than a suppression-target tissue which is a target to be suppressed is low on the second calculated image as compared to the first calculated image. The processing circuitry is configured to generate a difference image between the first calculated image and second calculated image so as to generate an image on which a signal value of a tissue with a long relaxation time is suppressed.
