Abstract:
Objective To discuss the optimal imaging conditions of spatio-temporal image correlatin (STIC). Methods Conventional 2D fetal echocardiography and 3D STIC volume collection were performed in 130 fetuses. The images obtained using two methods were scored and compared. Results Complete 3D volume collection with the initial view of four chamber view were abtained in 121 fetuses, the successful rate was 93.13%. There was no significant differences in total score between the two methods. Significant difference was found between the score of different condition groups.The highest scores mostly appeared in lateral four chamber heart in both method groups. The highest scores mostly appeared in 25-29 gestational weeks with 2D ultrasound, while 20-24 gestational weeks with 3D ultrasound, scores in long axis views of vessels were statistically different. Conclusion STIC has advantages over conventional ultrasonography, but needs conditions control and analysis skills.
