Abstract:
Objective: To explore the application value of spatiotemporal image correlation (STIC) combined with 5D Heart intelligent navigation echocardiography in ultrasonic screening of normal fetuses. Methods: Ultrasonic screening of fetal heart was performed in 114 normal fetuses using conventional two-dimensional ultrasound and STIC combined with 5D Heart intelligent navigation technique by doctor A. The time taken for image collection using these two methods were recorded and the same nine sections were scored. One week later, image quality of STIC combined with 5D Heart was scored again by doctor A again, also by doctor B. The qualified rate of each section was compared between the two methods, and the consistency of image quality score by the same doctor and different doctors was analyzed. Results: Two fetuses were excluded due to obvious fetal movement and inability to determine the position of the intelligent navigation point. The time of collection of fetal heart volume images and conventional two-dimension ultrasound images were (94.76±35.21)s and (595.88±139.29)s, respectively (P<0.001). There was no statistical difference between two examination methods in the qualification rate of the four-chamber, five-chamber, right ventricular outflow tract, three vessel and trachea, aortic-arch nor ductal-arch sections (all P>0.05). The qualification rate of the abdomen and left ventricular outflow tract sections using STIC combined with 5D Heart was lower than those using the conventional two-dimension ultrasound (both P<0.05). The score of each slice had good consistent between different doctors (except for three-vessel trachea and aotic-arch sections) and the same doctor except for aotic-arch section who analyzed the volume data at different times (all Kappa>0.75). Conclusion: STIC combined with 5D-Heart intelligent navigation technique can shorten the examination time. The quality of the nine fetal heart view images can meet the needs of fetal heart ultrasonic screening, feasible and repeatable in normal fetal heart ultrasonic screening.
