An ultrasonic diagnostic apparatus 1 capable of displaying an image having considered two or more parameters of parameters each indicative of a state of inflow of a contrast agent and parameters each indicative of outflow of the contrast agent is provided. The ultrasonic diagnostic apparatus 1 is equipped with a display controller which causes a parametric image generated using a two-dimensional map MP1 taking as axes, an arrival time T1 taken until a contrast agent arrives and an outflow time T2 taken until the contrast agent flows out, for example, of parameters each indicative of a state of inflow of the contrast agent administered to a subject and parameters each indicative of a state of outflow of the contrast agent, to be displayed based on the arrival time T1 and the outflow time T2. The parameter indicative of the state of inflow of the contrast agent may be an inflow rate of the contrast agent at a portion at which the contrast agent has arrived.
