Quantitative tissue velocity imaging in assessing auricular wall motion of normal fetuses
Abstract：Objective To assess the value of quantitative tissue velocity imaging(QTVI) in assessing the auricular wall motion of normal fetuses.Methods Fifty two normal fetuses from the 21st gestation week to the 28th gestation week underwent QTVI.The peak velocities were measured in the basal and mid parts of the left and right free auricular wall on the apical four-chamber view.The peak sustained systolic velocity (Vs),peak early diastolic (Ve) and peak late diastolic velocity (Va) were measured and compared between left and right auricular.Results The tissue velocity imaging curve consisted of "s","e" and "a" peak.The peak velocities of "a" peak was higher than that of "e" peak in both the basal part and the mid part in the left and right auricular.The peak velocities of the basal part were higher than those of the mid part in the left and right free auricular wall.The peak velocities of right free auricular wall were higher than those of left free auricular wall in both the basal part [Vs:(3.40 ±0.89) cm/s vs (2.19 ±0.64) cm/s,Ve:(2.26 ± 1.16) cm/s vs (1.14 ±0.62) cm/s,Va:(6.34 ± 1.09) cm/s vs (3.70±1.19) cm/s] and the mid part [Vs:(1.95 ±0.87)cm/s vs (1.43 ±0.62)cm/s,Ve:(0.99±0.64)cm/s vs (0.43 ±0.29) cm/s,Va:(3.37 ±1.31) cm/s vs (1.39 ±0.78)cm/s] (all P＜ 0.05).Conclusion QTVI is feasible in assessing the auricular wall motion and function of the normal fetuses.
