Reliable measurements of the fetal lung volume are important for the prenatal assessment of various pathologies impacting fetal lung development. Here we compare the inter-rater reliability of fetal lung volume measurements segmented from native ssFSE scans to those from high-resolution fetal body reconstructions to determine if the high-resolution reconstructions provide a clinical benefit. We find that there is increased reliability in the volumes segmented from the high-resolution reconstructions, suggesting that high resolution reconstruction of the fetal lungs may enable more precise assessments of fetal lung volume.
