Methods The lung-to-liver intensity ratio was calculated by means of region-of-interest analysis in all 35 fetuses including 7 bilateral urinary anomalies, 9 unilateral urinary anomalies, 5 pulmonary anomalies, and 14 others. Results All fetuses with urinary anomalies and pulmonary anomalies showed low ratio of lung-to-liver signal intensity. Conclusion Low ratio of lung-to-liver signal intensity on MR imaging indicates pulmonary hypoplasia after 22 weeks’ gestation.展开更多
