Purpose Fetal cardiac MRI (fCMR) is an emerging diagnostic tool for evaluating congenital heart disease (CHD), particularly when ultrasound (US) encounters limitations.The diagnostic pathway for fetal heart diseases begins with a screening morphological US.A comprehensive anatomical evaluation is essential for a complete prenatal diagnosis of CHD, as it plays a crucial role in parental counseling, postnatal treatment planning, and outcome assessment. When CHD is suspected during routine midtrimester US screening, a detailed fetal echocardiogram represents the primary diagnostic tool for accurately...
Read more Methods and materials Study population:A total of 29 fetuses, with a gestational age greater than 30 weeks and without fetal known cardiac abnormalities, were enrolled in this study between November 2023 to December 2024.The patients underwent MRI for other fetal pathologies, including central nervous system abnormalities, infections and placental disorders.The absence of cardiac abnormalities was supported by normal heart anatomy on fetal echocardiograms in these patients.fCMR protocols:fCMR exams were performed using a 3.0T scanner (Magnetom Vida, Siemens), with participants positioned in a supine...
Read more Results Six patients were excluded from the analysis because of stochastic fetal movements and movement artifacts; therefore, the study population was composed of 23 patients.Mean gestational age was 32 ± 3.Table 1 shows main volumes and function for LV for both 4-chambers and short axis view. A significant difference was observed in LV end-diastolic volume (LV-EDV) and LV end-systolic volume (LV-ESV), with values being higher in the short-axis view (LV-EDV: 2.3 ± 1.2 mL; LV-ESV: 1.1±0.5) compared to the four-chamber view...
Read more Conclusion 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.7This study demonstrates that both four-chamber and short-axis views provide comparable volumetric measurements for the fetal...
