From: Which is more accurate measuring pulmonary artery resistance index or 4D lung volume for prediction of neonatal respiratory distress in preterm pregnancies?

Fig. 2

AC Lung volume of pregnant patient 23 years old, GA = (34 wks + 0 ds) calculated by 3D US using VOCAL technique showing: the volume of right lung (A) and left lung (B) 31 cm3 and 29 cm3, respectively. C The pulmonary artery resistance index (RI) of the same patient measured by pulsed Doppler RI = 0.74. (Neonate with mild RD admitted to ICU for 2 days)
