Evaluation of fetal foramen ovale blood flow by pulsed Doppler ultrasonography combined with spatiotemporal image correlation

Evaluation of normal fetal ductus venosus using B-flow imaging with spatiotemporal image correlation and traditional color Doppler echocardiography.

OBJECTIVE To explore the feasibility of using four-dimensional echocardiography with B-flow and spatiotemporal image correlation (4DBF-STIC) imaging technology to detect fetal ductus venosus (DV), and establish the normal reference range for the ductus venosus diameter at 18-40 weeks gestation. METHODS This was a prospective observational study to detect the DV in 354 normal fetuses at 18-40 ...

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

Pulsed Doppler: Diameter, Blood Flow Velocity

Diameter, blood flow velocity and volumic flow of the brachial artery were measured in 36 patients with sustained essential hypertension and compared with 25 normal subjects. Both hypertensives and control subjects were classified according to age into those younger than and those older than 40 years. For the determinations, a pulsed Doppler velocimeter with an adjustable range-gated time syste...

Transcranial doppler ultrasonography should it be the first choice for persistent foramen ovale screening?

BACKGROUND Persistent foramen ovale (PFO) is considered a cause of cryptogenic stroke and a risk factor for neurological events in young patients. The reference standard for identifying a PFO is contrast-enhanced transesophageal echocardiography (TEE).The goal of this study was to evaluate the feasibility of transcranial color Doppler (TCD) and its diagnostic sensitivity compared with TEE. ME...
