Prognosis of isolated congenital diaphragmatic hernia using lung‐area‐to‐head‐circumference ratio: variability across centers in a national perinatal network

Our results show that o/e-LHR measured on two-dimensional ultrasound is a good indicator of neonatal prognosis in cases of CDH that may be used even in fetal medicine centers with a small caseload. However, our results also suggest that LHR measurement may be difficult to perform correctly. Therefore, appropriate training should be offered to professionals. Copyright © 2017 ISUOG.
