An ultrasound method and system for measuring perfusion of a tissue of interest during an ultrasound examination is provided. Perfusion within a region of a tissue can be accurately quantified by measuring a concentration level of contrast agent in a first region before and after reducing the concentration level of contrast agent in a second region. The position of the second region overlaps the position of the first region such that any dimension of the second region differs from any corresponding dimension of the first region by less than a factor of two. With these concentration measurements, contrast agent flow into the first region can be calculated. A corresponding ultrasound image can be created that qualitatively displays perfusion of the tissue.
