3-D Ultrasound images of normal fetal spine:
*Sonography of fetal spine using 3-D/ 4-D ultrasound reveals greater detail of the fetal spine in 3-Dimensions. Ultrasound visualizes the ossified part of the fetal spine. The 3 main ossification centers in the fetal vertebrae are:
a) the centrum b) the right neural process and c) the left neural process.
The centrum forms the central part of the vertebral body. The postero-lateral parts of the vertebrae are formed by the right and left neural processes. (These 3-D ultrasound images are courtesy of Dr. PK Srivastava, India, and Dr. Ravi Kadasne, UAE).
