【摘要】：【目的】通过分析心脏各标准切面显示率的一致性及心脏、大血管径线测量的可靠性来评估四维超声时间空间关联成像(STIC)技术进行早孕末期胎儿心脏检查的可行性。【方法】病例来自我院2012年2月-2013年6月进行早孕末期(11-13+6周)颈后皮层超声测量并经随访心脏结构正常的胎儿115例。获取胎儿心脏四维STIC容积后由两名研究者离线分析。比较胎儿心脏各标准切面的显示率;检验心脏各标准切面显示率的组间及组内一致性及心脏、大血管径线测量的组间及组内可靠性。【结果】心脏检查完成率均达85%以上。灰阶及彩色多普勒(CDFI)条件下四腔心、左右室流出道切面的显示率达97%和85%以上;而三血管切面的显示率在灰阶条件为50%,联合CDFI技术后提高到85%。各标准切面显示率组间一致性К值分别为0.82~0.96;组内一致性К值分别为0.86~0.99。心脏横径、面积、周长;左、右心室内径;主、肺动脉内径组间测量的同类相关系数(ICC)为0.86~0.99,组内ICC为0.9~0.99。室间隔厚径、主动脉弓峡部内径、动脉导管弓内径组间测量的ICC为0.45~0.55,组内ICC为0.52~0.79。【结论】四维超声STIC技术可以显示早孕末期大部分胎儿心脏的标准筛查切面;STIC技术显示早孕末期胎儿心脏各标准切面及测量心脏、大血管径线均有良好组间及组内的一致性和可靠性。
[Abstract]:[objective] to analyze the consistency of the standard sections of the heart and the heart. The reliability of macrovascular diameters was used to evaluate the feasibility of fetal cardiac examination at the end of early pregnancy using four-dimensional ultrasound time-spatial correlation imaging (STICI). [methods] A case was performed in our hospital from February 2012 to June 2013. At 11-136 weeks, 115 fetuses with normal cardiac structure were measured by cortical ultrasonography and followed up. The four-dimensional STIC volume of the fetal heart was analyzed offline by two researchers. To compare the display rate of each standard section of fetal heart, to test the consistency of each standard section of the heart and the reliability of the heart, and to measure the intergroup and intra-group reliability of the great vessel diameter. [results] the complete rate of cardiac examination was more than 85%. Under gray scale and color Doppler flow imaging (CDFI), the display rate of left and right ventricular outflow tract section was more than 97% and 85%, while that of three-vessel section was 50% under gray scale condition and increased to 85% after CDFI technique. The concordance values of each standard section display rate among groups were 0.82 and 0.96, respectively, and the intra-group consistency values were 0.86 and 0.99, respectively. The same correlation coefficient measured between the left and right ventricular diameter and pulmonary artery diameter group was 0.86 ~ 0.99, and the ICC in the group was 0.90.99. The diameter, area, circumference, left and right ventricular diameter of the heart were 0.86, 0.99 and 0.90.99, respectively, and the correlation coefficients between the two groups were 0.86 and 0.99, respectively. Thickness of ventricular septum, inner diameter of isthmus of aortic arch, The ICC measured between groups of ductus arteriosus was 0.45 卤0.55, and the ICC of group was 0.52 卤0.79. [conclusion] Four-dimensional ultrasound STIC can display the standard screening section of most fetal heart in the late stage of early pregnancy. The STIC technique can show the standard section of fetal heart and measure the heart at the end of early pregnancy. There was good consistency and reliability among groups and within groups.
