Abstract: In a method and apparatus for examination and evaluation of a blood flow in a pulmonary artery of a patient, measurement data are recorded, from which at least a part of the blood flow in the pulmonary artery is able to be re-constructed at least two-dimensionally in a plane defined by a longitudinal axis of the pulmonary artery and by an anterior-posterior direction, including at least at several diastolic points in time in the course of a heart cycle, after a closure of the pulmonary valve. The number of diastolic points for which an asymmetry in relation to the longitudinal axis of the pulmonary artery in the anterior-posterior direction exists is determined. A measure is then determined that characterizes how long, after the closure of the pulmonary valve, the aforementioned asymmetry exists.

Abstract: In a method and apparatus for examination and evaluation of a human or animal body as regards a blood flow in a pulmonary artery (PA), measurement data are recorded, from which at least a part of the blood flow in the pulmonary artery (PA) is able to be re-constructed at least two-dimensionally in a plane defined by a longitudinal axis of the pulmonary artery (PA) and by an anterior-posterior direction, including at least at several diastolic points in time in the course of a heart cycle, after a closure of the pulmonary valve. The measurement data are analyzed as to how many of the at least several diastolic points in time in the flow behavior of the blood flow of the pulmonary artery an asymmetry in relation to the longitudinal axis of the pulmonary artery in the anterior-posterior direction exists. A measure is then determined that characterizes how long, after the closure of the pulmonary valve in the flow behavior of the blood flow of the pulmonary artery, the aforementioned asymmetry exists.
