Abstract:

Magnetic Resonance Imaging (MRI) has important research value in the diagnosis of fetal bone abnormalities in the second trimester. At present, the diagnosis is faced with the challenges of accuracy and impact assessment on pregnancy outcome, and traditional prenatal B-ultrasonography has certain limitations in diagnostic efficiency. In this study, from January 2021 to January 2024, 58 women in the second trimester of pregnancy who were confirmed to have fetal bone abnormalities after labor induction or delivery were studied. Compared with B-ultrasound, MRI showed a higher number of fetal bone abnormalities detected, labor induction rate and overall excellent image quality rate. MRI has significant value in the diagnosis of fetal bone abnormalities in the second trimester, and can provide reliable fetal bone information for pregnant women and their families, which is conducive to improving pregnancy outcomes and ensuring good birth and fertility, and has broad clinical application prospects.
