Online versus offline spatiotemporal image correlation (STIC) M-mode for the evaluation of cardiac longitudinal annular displacement in fetal growth restriction

Fetal cardiac function: M-mode and 4D spatiotemporal image correlation.

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 counsel...

New Insight from Using Spatiotemporal Image Correlation in Prenatal Screening of Fetal Conotruncal Defects

Spatio-temporal Image Correlation (stic): a New Technique for Fetal Heart Evaluation*

Although congenital heart defect is the most frequent anomaly in newborns, its antenatal detection rate through conventional ultrasound remains low. 3D and 4D ultrasound technology was developed early in the nineties, bringing great benefits in obstetrics, especially in cases of dubious diagnosis at 2D ultrasound. The spatiotemporal image correlation (STIC) is a significant development in the f...

Evaluation of right ventricular function in fetal hypoplastic left heart syndrome using spatio-temporal image correlation (STIC).

BACKGROUND Postnatal outcome of fetuses with hypoplastic left heart syndrome (HLHS) is mainly determined by right ventricular function. In the present study we used spatio-temporal image correlation (STIC) to assess right ventricular function of fetuses with HLHS. METHODS Three-dimensional ultrasound with STIC technique was used to acquire heart images from fetuses that had HLHS and the norma...

Fetal cardiac output and ejection fraction by spatio-temporal image correlation (STIC): comparison between male and female fetuses.

OBJECTIVE To compare the cardiac output (CO) and ejection fraction (EF) of the heart of male and female fetuses obtained by 3D-ultrasonography using spatio-temporal image correlation (STIC). METHODS We conducted a cross-sectional study with 216 normal fetuses, between 20 and 34 weeks of gestation, 108 male and 108 female. Ventricular volumes at the end of systole and diastole were obtained by...
