According to one embodiment, a medical image diagnostic apparatus includes a display and processing circuitry. The display displays a relationship diagram indicating a relationship between values which are respectively set for imaging parameters relating to an imaging condition of medical imaging. The processing circuitry updates the relationship diagram in accordance with a moving operation of a point corresponding to each of the values on the relationship diagram, or a change operation of the imaging condition. The processing circuitry changes the imaging condition before the moving operation or the change operation to an imaging condition which reflects the moving operation or the change operation.
