An ultrasound diagnostic apparatus for use in the imaging or characterization of biological tissue, including an ultrasonic probe, a gate circuit, a spectrum analysis device, a computation device and a display. The ultrasonic probe emits ultrasonic beams and receives the reflected echo signals from tissue interfaces. The reflected signals are sampled by the gate circuit and are Fourier-analyzed by the spectrum analysis device, and then the computation device derives frequency-dependant ultrasonic attenuation properties therefrom. The results of the computation device are displayed by the display to indicate the state of the tissue.
