Application study of an intelligent three-dimensional ultrasound imaging in obtaining for fetal cranial mid-sagittal view / 中华超声影像学杂志

ABSTRACT

Objective To evaluate the feasibility of an intelligent three-dimensional ultrasound technique (Smart mid-sagittal planes,Smart MSP) in automatically detecting the fetal cranial mid-sagittal view.Methods Two hundred and forty pregnant women with singleton pregnancies were imaged to display the mid-sagittal view of fetal head using the Smart MSP by six doctors divided into three groups according the different experiences.Another two doctors were then invited to score the images acquired and to compare the successful rates of 6 doctors for acquiring fetal cranial mild-sagittal view according to the doctors' experience.Results The overall successful rate of acquiring the mid-sagittal view was 97.08％ (233/240) with the bipartial diameter plane (BPD plane) as the starting plane and 98.33(237/240) with the trans-cerebellum plane as the starting plane by using Smart MSP program.The successful rates in three groups were similar but the consumed times were different(P ＜0.05).The experienced doctors consumed less time than non-experienced doctors.The scores were also different in three groups.The scores of experienced doctors (group B and C) were significantly higher than that of non-experienced doctors (Group A) (P ＜0.05).There was no significant difference in the scores between experienced doctors (group B and C) (P＞0.05).Conclusions Smart MSP is a novel and feasible method for the automatic visualization of fetal cranial mid-sagittal plane,which may become an effective tool to screen the fetal midline anomalies in future.
