Abstract

PURPOSE: To measure changes in normal fetal lung volume with increasing gestation by using echo-planar magnetic resonance (MR) imaging. MATERIALS AND METHODS: Fifty-six singleton fetuses were examined longitudinally with respect to lung volume by using echo-planar MR imaging between 19 weeks gestation and term. RESULTS: Lung volume increased exponentially with gestation from 8 to 125 mL. Volume was related to gestation by using the equation, volume = 0.8375e(0.1249g) (R-2 = 0.77), where g = gestation. Lung volume had a direct relationship to fetal volume with increasing gestation (R-2 = 0.75). There was no significant relationship between amniotic fluid volume and lung volume (R-2 = 0.11). CONCLUSION: Variation in lung volumes can be assessed by using echo-planarMR imaging, regardless of variations in amniotic fluid volume. These measurements are less than those obtained from postmortem and neonatal studies but are similar to those obtained by using three-dimensional ultrasonography. Lung volume estimations obtained by using echo-planar imaging may have important clinical and research applications when noninvasive assessment of lung volume is required.
