Provided arc an ultrasound diagnosis apparatus and a method of controlling an ultrasound diagnosis apparatus capable of improving diagnosis accuracy of a user for a subject.An ultrasound diagnosis apparatus (1) includes an ultrasound probe (21) that has a transducer array (2), an imaging unit (11) that performs transmission and reception of an ultrasonic beam from the transducer array (2) toward a subject, into which contrast media including microbubbles is introduced, and images a reception signal output from the transducer array (2) to generate an ultrasound image, a display unit (7) that displays the generated ultrasound image, a bubble tracking unit (8) that tracks movement of the microbubbles based on the ultrasound image generated corresponding to one section to acquire trajectories of the microbubbles in the one section and displays the acquired trajectories on the display unit (7), and a feature point detection unit (9) that detects, as a feature point, a trajectory, in which a distance between a start point and an end point in a prescribed time range is less than a prescribed, among the acquired trajectories of the microbubbles and displays the detected feature point on the display unit (7).
