| 目的 探讨时间-空间相关成像(STIC)技术在正常胎儿心脏超声检查中的成像方式及其临床应用价值。 方法 分别使用常规二维超声和STIC技术对120例孕龄在22~28周的正常胎儿进行心脏扫查,比较两种方法获得胎儿心脏图像的质量和扫查时间有无统计学差异,并分析STIC技术的成像方法。 结果 120例正常胎儿心脏均获得满意的容积图像,各切面图像的显示合格率与常规二维扫描图像的差异无统计学意义(P>0.05),且能显示出常规二维不能显示的切面。所研究的120例样本中,共有85例可计算常规二维超声筛查时间,平均每个胎儿心脏用时(5.26±2.01)min;共有104例可计算STIC扫描时间,平均每次STIC扫描用时(4.47±2.32)min。 结论 STIC技术比常规二维超声能提供更多的观察心脏解剖结构的切面和信息,可简化图像采集过程,缩短检查时间,减少对检查者经验的依赖,提高工作效率,同时大大减少胎儿心脏接受超声波照射的时间。 |

| Objective To explore the basic method and clinical application of spatio-temporal image correlation (STIC) in the routine scanning of normal fetal heart. Methods Totally 120 volume datasets of normal fetal heart were acquired with 2D and STIC, respectively. The difference in time between the two methods were compared and the basic imaging method was explored and analyzed. Results Satisfactory gray-scale volume acquisitions were accomplished in all 120 cases. The quality of the images derived from volume datasets were comparable to that directly obtained from 2D echocardiography. No significant difference of visualization rate was found between the two methods (P>0.05). Some views that could not be showed with 2D were acquired with STIC. In fetal heart screening, STIC (n=104) and routine ultrasonography (n=85) took (4.47±2.32) min and (5.26±2.01) min per case, respectively. Conclusion STIC provides more views and information than 2D, simplifies the picture-gathering process, decreases the dependence of examiner, increases the efficiency, and decreases the exposure upon fetal heart obviously. |
