An ultrasonic diagnostic apparatus (10) that performs high acoustic pressure and low acoustic pressure ultrasonic transmissions by switching at predetermined timing in the enhanced ultrasonography, and displays concurrently a replenishment image obtained through the low acoustic pressure transmission in real time like a moving picture, and a pre-flash image obtained through the low acoustic pressure transmission immediately before switching to the high acoustic pressure transmission like a still image to allow the operator to understand the structure at the level of capillaries. It is also possible to display a selected image obtained through the low acoustic pressure transmission at an arbitrary timing instead of the pre-flash image. <;IMAGE>;
