First-Trimester Fetal Cardiac Function Measurements Using Spatio-Temporal Image Correlation and Two Ultrasound-Related Post-Processing Methods: A Feasibility and Reproducibility Study.

ABSTRACT:

Objective

To study the feasibility and reproducibility of two ultrasound (US) related post-processing methods for first-trimester fetal cardiac function assessment by ventricle volume measurements.

Method

First-trimester transvaginal Spatio-Temporal Image Correlation (STIC) US datasets acquired between 11⁺⁰-13⁺⁶ weeks gestational age (GA) were used to perform fetal cardiac ventricle volume (FCVV) measurements in the end-diastolic (EDVV) and end-systolic (ESVV) phases using two methods: the manual segmentation method Virtual Organ Computed-Aided AnaLysis (VOCAL) and (semi-)automated volume measuring method Virtual Reality (VR). Reproducibility was assessed by calculating the intra-, interobserver and intersystem agreement using intraclass correlation coe
