An ultrasonic diagnostic apparatus of an embodiment includes processing circuitry. The processing circuitry is configured to acquire a B mode image in which a signal intensity of reflected waves obtained in such a manner that ultrasonic waves are transmitted to a scanning area in a subject and reflected in the subject is represented by luminance levels, and a Doppler image of a region of interest included in the scanning area. The processing circuitry is configured to cause a display to display the Doppler image superposed on the B mode image acquired. In addition, the processing circuitry is configured to change a display mode of the Doppler image displayed on the display using a feature quantity obtained on the basis of at least one of the B mode image and the Doppler image in a time series acquired.
