Abstract:
Objective To evaluate the value of tomographic ultrasound imaging(TUI)in the fetal heart screening.Methods One hundred and ten volume datasets acquired from normal fetal heart in the second trimester with spatio-temporal image correlation(STIC) were evaluated offline with TUI. The Bmode and CDFI static images as well as the dynamic loops of one cardiac eycle could be reviewed simultaneously. The visualizing rate and ultrasonic scores of the 4 chamber view,outflow tracts and 3 vessels (and trachea)view obtained from TUI and routine ultrasonography for fetal heart screening were respectively compared. Results Among all 110 cases,the visualizing rate of 4 chamber view,outflow tracts and 3 vessels(and trachea) view were respectively 100%(67),88.9%(45),80.0%(45),84.4%(32)in Bmode and 100%(33),86.2%(25),50.0%(14),100%(4)in CDFI under the same fetal Dositi.n.No significant differences of the visualization rate were found between TUI and routine screening either in Bmode or in CDFI(P＞0.05). The median score of 4 chamber view of TUI in B-mode was little higher than that in routine screening,while the right outflow tract of screening in CDFI significantly higher than that of TUI(P＜0.05). Conclusions The visualizing rates and qualities of TUI are sufficient for fetal heart screening offline as well as routine ultrasonography online in second trimester.
