In an ultrasonic diagnostic apparatus, ultrasonic pulse beams are transmitted into an organism, ultrasonic waves reflected within the organism are received to obtain received signals, and an image is displayed in accordance with the received signals thus obtained. The ultrasonic diagnostic apparatus has a blood flow velocity arithmetic unit for extracting a Doppler transition component of the reflected ultrasonic waves in accordance with the received signals to evaluate a distribution of a velocity of a blood flow within the organism in accordance with the extracted Doppler transition component; a blood flow power arithmetic unit for extracting a Doppler transition component of the reflected ultrasonic waves in accordance with the received signals to evaluate a distribution of a power of a blood flow within the organism in accordance with the extracted Doppler transition component; and an image display unit for simultaneously displaying on a display screen a first image representative of a blood flow velocity distribution evaluated by said blood flow velocity arithmetic unit, and a second image representative of a blood flow power distribution evaluated by said blood flow power arithmetic unit.
