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

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

BACKGROUND : To establish the reference range of the angle between ascending aorta and main pulmonary artery of fetus in the second and third trimester using spatiotemporal image correlation (STIC), and to investigate the value of this angle in prenatal screening of conotruncal defects (CTDs). MATERIALS AND METHODS Volume images of 311 normal fetuses along with 20 fetuses with congenital hear...

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...

Feasibility Study on Prenatal Cardiac Screening Using Four-Dimensional Ultrasound with Spatiotemporal Image Correlation: A Multicenter Study

OBJECTIVE This study aimed at investigating the feasibility of using the spatiotemporal image correlation (STIC) technology for prenatal cardiac screening, finding factors that influence the offline evaluation of reconstructed fetal heart, and establishing an optimal acquisition scheme. METHODS The study included 452 gravidae presenting for routine screening at 3 maternity centers at 20-38 ge...

Guidelines for 22q11 deletion screening of patients with conotruncal defects.

Goldmuntz et al. (1) have reported the frequency of 22q11 deletions in a prospectively ascertained sample of 251 patients with conotruncal defects. Deletions were found in 17.9% of the patients, including 50% with interrupted aortic arch (IAA), 34.3% with truncus arteriosus (TA), and 15.9% with tetralogy of Fallot (TOF). Although this study was designed to determine the frequency of deletions i...

P-226: Non-Invasive Prenatal Screening for Fetal Chromosomal Anomalies in South of Iran

Background: Prenatal diagnosis for Fetal Chromosomal anomalies currently relies on assessment of risk followed by a combination of biochemical and nuchal translucency. Trisomy 21 is the most common trisomy that is associated with intellectual disability. Pregnant women who receive a prenatal diagnosis of trisomy 21 currently have the option of continuing or terminating their pregnancy, but no f...
