Final answer:
Ultrasound imaging is the technique of choice for studying fetal growth and development due to its ability to provide real-time visualization of the fetus and its organs, allowing for the identification of abnormalities and monitoring of important indicators like fetal growth and amniotic fluid volume.
Step-by-step explanation:
Ultrasound imaging is the technique of choice for studying fetal growth and development for several reasons. Firstly, it allows for the visualization of the fetus and its organs in real-time, providing detailed information about fetal anatomy. This can help identify any abnormalities or potential issues that may require medical intervention. Additionally, ultrasound can be used to assess fetal growth and monitor amniotic fluid volume, both of which are important indicators of fetal well-being.
