Abstract: An ultrasound imaging apparatus and a method of controlling the same are provided. The ultrasound imaging apparatus includes an ultrasound contrast agent (UCA) sensor configured to determine whether an UCA flows in an object based on an echo signal that is reflected by the object in a mechanical index environment. The ultrasound imaging apparatus further includes a controller configured to obtain at least one among an UCA image and a tissue image of the object in another mechanical index environment lower than the mechanical index environment in response to the UCA sensor determining that the UCA flows in the object.
