Non-invasive Diagnosis of Fetal Lung Prematurity with GLHW Ultrasound Tissue Characterization

Maeda K* and Serizawa M

Non-invasive diagnosis of fetal lung immaturity. Ultrasound gray level histogram width (GLHW) tissue characterization was studied in fetal lung. GLHW ratio of fetal lung and liver was multiplied by gestational weeks, and fetal lung immaturity was diagnosed, if the product was less than 29. Ninety six per cent of neonatal respiratory distress syndrome (RDS) was predicted noninvasively in immature fetal lung diagnosed by GLHW tissue characterization. Fetal lung immaturity diagnosed by GLHW ultrasound tissue characterization predicted neonatal RDS noninvasively.
