| 目的 探讨时间空间关联成像(STIC)技术应用于胎儿心脏的最优成像条件。 方法 对130胎正常胎儿心脏分别进行常规二维超声心动图检查以及三维STIC容积数据采集,脱机分析后进行显示效果评分,对显示效果进行比较分析。 结果 121胎胎儿完成三维容积数据采集,采集成功率为93.13%;常规二维超声心动图检查及三维STIC容积数据采集方法整体显示效果差异无统计学意义,同一方法在不同采集条件下的显示效果差异有统计学意义:两种方法均在侧位四腔心切面显示最佳,二维切面在妊娠25~29周显示率较高,三维切面在妊娠20~24周显示率较高;两种方法在血管长轴相关切面显示评分差异有统计学意义。 结论 STIC技术应用于胎儿心脏检查较常规二维超声检查具有优势,但需要对采集条件进行控制并熟练掌握脱机分析方法。 |

| 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. |
