An image processing apparatus according to an embodiment includes processing circuitry. The processing circuitry is configured to obtain pixel values of at least three Magnetic Resonance (MR) images of mutually-different types. The processing circuitry is configured to generate a scatter diagram in which values based on the pixel values are arranged in a region having at least three-dimensional axes and which displays a value group related to a target tissue in such a manner that a value group related to a specific target serving as a reference is always displayed in the same position, and then cause a display to display the scatter diagram.
