Factors such as maternal obesity, oligohydramnios, fetal position, or calcified ribs can compromise acoustic windows, reducing the effectiveness of US. fCMR provides a comprehensive assessment of cardiac anatomy and function, as well as the great vessels, while also enabling the detection of additional anomalies. Moreover, by analyzing blood flow dynamics, fCMR represents a potential tool for identifying abnormalities in fetal brain development and placental perfusion.7
This study demonstrates that both four-chamber and short-axis views provide comparable volumetric measurements for the fetal LV, except for LV-EDV and LV-ESV, which showed a significant discrepancy. The similarity in measurements allows for interchangeable use of both views in clinical practice.
LIMITATIONS OF THE STUDY: Due to the monocentric nature and the limited sample size, further multicentric studies with larger populations are needed to confirm these findings.
