The aim of this study was to compare fetal lung elastography (FAE) values between groups with and without Respiratory Distress Syndrome (RDS) in preterm neonates and to evaluate the potential of FAE to predict the risk of developing RDS.
The evaluate the potential of fetal lung elastography as a non-invasive method to predict and treatment respiratory complications in preterm neonates. FAE is an imaging method that measures the elasticity properties of fetal lung tissue using ultrasound technology. This method can be helpful in providing information about the development and respiratory function of the fetal lungs.
The advantages of FAE are:
It is a non-invasive method: FAE is performed using ultrasound technology and has no known maternal or fetal harm. It stands as a potentially safe method compared to current invasive tests.
It is cost-effective and easy to perform: FAE is a procedure performed using existing ultrasound equipment at no separate cost. Therefore, it can be easily implemented and repeated in clinical settings.
Fast results: FAE provides fast results by acquiring images in real time. This indicates that FAE can be a valuable diagnostic tool in emergency situations or when rapid decision-making is required.
A potential predictive tool: The results of this study may indicate that FAE values are a potential tool for predicting the risk of developing RDS. This could be an important step to develop early diagnosis and treatment strategies to improve the respiratory health of preterm newborns.

The study will include single pregnant women with maternal age of 18-45 years, gestational age between 24-34 weeks, diagnosed with preterm labor, amniotic fluid pathology, fetal congenital and chromosomal anomalies, and fetuses without fetal congenital and chromosomal anomalies, who were hospitalized in the ward after the application to the Perinatology Clinic of Etlik City Hospital. A total of 80 patients without systemic maternal disease findings and diagnoses, without chronic drug use, who were measured at least 24 hours after antenatal corticosteroids were administered and delivered within a maximum of 72 hours, will be included in our study as two case groups with and without RDS diagnosis in neonatal follow-up.
Exclusion Criteria:
A total of 80 patients with no systemic maternal disease findings and diagnoses, without chronic drug use, who were measured at least 24 hours after antenatal corticosteroids were administered during pregnancy, and whose delivery occurred within a maximum of 72 hours, will be included in our study as two case groups with and without RDS diagnosis in neonatal follow-up.
Diagnostic Test: fetal lung elastography measurement
A total of 80 patients with no systemic maternal disease findings and diagnoses, without chronic drug use, who were measured at least 24 hours after antenatal corticosteroids were administered during pregnancy, and whose delivery occurred within a maximum of 72 hours, will be included in our study as two case groups with and without RDS diagnosis in neonatal follow-up.
Diagnostic Test: fetal lung elastography measurement
Elastography measurements are planned to be performed as in the studies "Feasibility of two-dimensional ultrasound shear wave elastography of human fetal lungs and liver: A pilot study" and "Feasibility of 2-D ultrasound shear wave elastography of fetal lungs in case of threatened preterm labour: a study protocol" in the literature examples section of the file.
Fetal Lung Elastography Measurement
Measurement of prenatal ultrasonographic shear wave elastographic values(kPa) of the fetus in cases of preterm labor
Time frame: Prenatal (24-34 gestational weeks, before 72 hours to delivery)
