Objective. The purpose of this study was to test the possibility of diagnosing ventricular septal defects (VSDs) by using tomographic ultrasound imaging (TUI) on 4-dimensional volumes of the fetal chest obtained with spatiotemporal image correlation and the color Doppler function. Methods. We retrospectively evaluated the 4-dimensional spatiotemporal image correlation volumes of 8 fetuses with VSDs (single in 7 and double in 1) between 20 and 33 weeks' gestation. The data were analyzed to determine whether VSDs were correctly identified in at least 1 of 7 automatically generated TUI displays. Results. All of the included VSDs were correctly identified with the use of an interslice distance in the TUI function ranging from 0.8 to 2 mm without the need to further manipulate the volume.Conclusions. This automatic approach shows good retrieval of diagnostic cardiac planes in fetuses with VSDs, which may improve the diagnostic accuracy for this disease.

“…3). 3D/4D US is most often applied to fetal heart functional evaluation with the goal of obtaining ventricular volumes to extrapolate fetal SV (velocity time integral × valve area, a calculation of the volume of blood flow out of the heart at systole), EF (SV/end-diastolic volume), and CO (SV × heart rate) [13,14,15,16,17,18]. Ventricle volumetry may be applied to the evaluation of suspected CHD with disturbance of ventricle size, such as cardiomegaly and cardiomyopathy, stenotic aortic valve and evolving hypoplastic left heart syndrome, or Ebstein anomaly.…”

Fetal Cardiac Function: M-Mode and 4D Spatiotemporal Image Correlation

et al. 2012

Fetal cardiac function has been shown to be a marker of disease severity in many conditions, including intrauterine growth restriction, congenital heart defects or disease (CHD), twin-to-twin transfusion syndrome, idiopathic hydrops, fetal arrhythmias, and others. It is often targeted for evaluation of patient management, for providing complete and accurate diagnoses in CHD, for patient counseling, or in referring for fetal cardiac interventions. In this review we will describe the use of M-mode and 4D spatiotemporal image correlation in fetal cardiac evaluation, the parameters that can be measured, and their application to clinical practice.

“…Moreover, the different techniques have acceptable intra- and interobserver variability [12,13,14,15,16,17]. Different groups have published nomograms for stroke volume and cardiac output, based on relatively large series of healthy fetuses [12,15,16,17]. In the current study, we aimed to evaluate the correlations between the three most commonly used 3D algorithms and the conventional Doppler method for cardiac output measurement.…”

“…Extensive research has focused on validating 3D ventricular volume measurements both in vitro and in vivo and demonstrated that 3D ultrasound volume measurements correspond well to the actual volume.

Objective: Fetal cardiac output is conventionally measured using two-dimensional (2D) and Doppler ultrasound (Doppler). New methods based on 3D measurements of ventricular size in systole and diastole have been proposed. Our aim was to validate these tools against the conventional Doppler-based methods. Methods: Fetal combined cardiac output was prospectively measured at 16, 20, and 24 weeks of gestation in 15 uncomplicated pregnancies using Doppler and three different 3D algorithms [virtual organ computer-aided analysis (VOCAL), sonographic automatic volume calculation (SonoAVC), and inversion mode]. We determined the inter- and intraobserver variability of the 3D techniques and assessed the correlation between Doppler and 3D. Results: The 3D techniques showed adequate inter- and intraobserver reproducibility (intraclass correlation coefficient 0.69–0.98), with the best reproducibility for SonoAVC and inversion mode. Bland-Altman analysis revealed low bias and relatively good correlations when comparing the 3D methods among each other, albeit with wide 95% confidence intervals. Doppler measurement of fetal weight-adjusted combined cardiac output (349.0 ml·min^–1·kg^–1) yielded significantly higher results than 3D CO measurements (177.2, 160.7, and 174.0 ml·min^–1·kg^–1 for VOCAL, SonoAVC, and inversion mode, respectively; p < 0.0001) and correlated poorly with the 3D methods. Conclusions: Although 3D volume-based cardiac output measurements are reproducible, results obtained with different methods are not interchangeable. SonoAVC and inversion have the highest intra- and interobserver reproducibility. Results of cardiac output measurement by 3D and Doppler cannot be interchanged.

Fetal cardiac stroke volume determination by four‐dimensional ultrasound with spatio‐temporal image correlation compared with two‐dimensional and Doppler ultrasonography

Abstract: There is a good agreement between SV measured either by 2D Doppler or by 4D STIC. The 4D STIC represents a simple and rapid technique to estimate fetal SV and promises to become the method of choice.
