Does Velocity Vector Imaging (VVI) allow for the measurement of global longitudinal cardiac strain and strain rate in fetuses?
Velocity Vector Imaging is a feasible tool for measuring global longitudinal cardiac strain and strain rate in fetuses, offering a potential angle-independent method to quantitate fetal cardiac function.
Barker et al. (2008) studied this question.
