“…We evaluated the volume quality referenced in the scoring system by Goncalves et al [20] and found that the mean score for the third trimester was significantly lower than the second trimester. The detection rate was likely correlated to volume quality, which was consistent with previous report [33]. As a retrospective study, we did not evaluate the acquisition quality as some factors (i.e., fetal movement) were not recorded.…”

BackgroundIdentification of prenatal ventriculoarterial connections in fetuses with conotruncal anomalies (CTA) remains one of the greatest challenges for sonographers performing screening examinations. Herein, we propose a novel protocol of 4D volume analysis that identifies ventriculoarterial connections and evaluate its clinical utility in routine screenings.MethodsTwenty-nine cases of transposition of the great arteries (TGA), 22 cases of double-outlet right ventricle (DORV), 36 cases of tetralogy of Fallot (TOF), 14 cases of truncus arteriosus (TCA), and randomly selected 70 normal fetuses were reviewed in this study. All cases were evaluated using 2D data alone (2D method), post-processing volumes with no exact algorithm (4D-1 method), or with the proposed algorithm (4D-2 method), or using the 2D and 4D data together (combined method). Comparisons were made to evaluate the detection rate of ventriculoarterial connections for these different methods.ResultsDuring 18–28 gestational weeks, the detection rate of 4D-2 modality was satisfactory. The detection rate of the combined method was significantly higher than 2D method in the identification of TGA, TOF, and TCA. The detection rate of 4D-1 method was significantly lower than 4D −2 modality for CTA fetuses. During late pregnancy, the detection rate for both 4D modalities was very low due to the poor quality of the 4D volumes.ConclusionsWe proposed a detailed protocol, which allowed the examiner to identify fetal ventriculoarterial connections by 4D volumes. Inclusion of blood information into the volumes improved diagnosis. Our findings suggest that the incorporation of 4D STIC into routine screenings could improve the detection for TGA, TOF, and TCA.Electronic supplementary materialThe online version of this article (doi:10.1186/s12947-017-0108-5) contains supplementary material, which is available to authorized users.

“…When the volume data set is suboptimal, subsequent analysis will be hindered by low image quality and artifacts. Indeed, investigators have demonstrated that: (1) the ability to visualize fetal cardiac structures is correlated with STIC volume quality 127 ; (2) a positive correlation exists between the “acquisition condition score” (score assigned to fetal movements, ROI setting, acquisition angle, cardiac apex position, and shadowing) and “quality” of STIC volumes 36 ; specifically, the higher the acquisition condition score, the better the volume “quality” (based on the ability to display cardiac structures); and (3) in a multicenter study of 4D fetal echocardiography in the first trimester, centers that reviewed a higher (versus lower) percentage of suboptimal STIC volumes had lower accuracy for identifying CHD 22 …”

“…It is noteworthy, however, that volumes of superior quality can still be obtained throughout the third trimester, even up to 39 weeks' gestation 90 . Moreover, in the first and early second trimesters, a detailed evaluation of both normal and abnormal fetal hearts using STIC technology can be performed 22 , 47 , 49 , 127 , 131 , 137 . This fact is clinically relevant, due to the increasing role of first‐trimester fetal cardiac examination 138 – 143 (eg, increased nuchal translucency thickness in the presence of a normal fetal karyotype).…”

Four-dimensional sonography with spatiotemporal image correlation (STIC) technology allows acquisition of a fetal cardiac volume data set and displays a cine loop of a complete single cardiac cycle in motion. Part 1 of this 2-part article reviews STIC technology and its features, the importance of operator training/experience, and acquisition of high-quality STIC volumes, as well as factors that affect STIC volume acquisition rates. We also propose a detailed and practical stepwise approach to performing 4-dimensional sonography with STIC and begin herein by providing general recommendations. Part 2 will discuss specifics of the approach, along with how to determine whether such volumes are appropriate for analysis.

“…A solid body of evidence suggests that 4D sonography with STIC facilitates examination of the fetal heart 3 , 4 , 5 , 11 – 37 and may also be used to evaluate fetal cardiac function 18 , 22 , 27 , 30 , 31 , 33 , 38 – 46 . This modality has also been used in the prenatal evaluation and diagnosis of congenital heart disease (CHD) 2 , 20 , 47 – 71 because it improves the ability to identify complex intracardiac relationships and can shorten the examination time 3 , 17 , 72 . These facts are important, since evaluation of the normal and abnormal fetal heart 73 – 75 using 2D sonography is one of the most challenging tasks in prenatal diagnosis.…”

The effective performance of fetal cardiac examination using spatiotemporal image correlation (STIC) technology requires 2 essential steps: volume acquisition and postprocessing. An important prerequisite is training sonologists to acquire high-quality volume data sets so that when analyzed, such volumes are informative. This article is part 2 of a series on 4-dimensional sonography with STIC. Part 1 focused on STIC technology and its features, the importance of operator training/experience and acquisition of high-quality STIC volumes, factors that affect STIC volume acquisition rates, and general recommendations on performing 4D sonography with STIC. In part 2, we discuss a detailed and practical stepwise approach for STIC volume acquisition, along with methods to determine whether such volumes are appropriate for analysis.
