Figure 1

Myocardial motion by tissue phase mapping. The vectors represent myocardial velocity, with magnitude indicated by the vector length and longitudinal (through plane) direction indicated by the vector color. Yellow denotes longitudinal contraction, and blue denotes longitudinal relaxation. Note the reduced magnitude of right ventricular systolic radial velocities in PAH compared with the healthy volunteer data, and prolonged right ventricular radial contraction in early diastole associated with septal shift.
