Mitral inflow velocities in one volunteer by all three techniques: (A) real-time phase contrast imaging (mean E, A, and E/A were 78cm/s, 25cm/s, and 3.1), (B) segmented phase contrast imaging (mean E, A, and E/A were 75cm/s, 27cm/s, and 2.8), and (C) Doppler echocardiography (mean E, A, and E/A were 77cm/s, 26cm/s, and 3.0).
