Two-dimensional shear wave elastography in determining the effects of lung and liver elasticity in normal third-trimester fetus

The first aim was to quantitatively evaluate fetal lung and liver elasticity between 28 and 40 weeks of gestation (WG) using two-dimensional(2D) shear wave elastography (SWE) and model fetal lung-to-liver elastography ratio (LLE). The secondary aim was to assess the impact of the depths between probe and target organs and explore the feasibility of establishing reference ranges for fetal lung and liver elasticity in the third trimester.
