Normal Anatomy of Fetal Spine in 4D Scan
3D/4D ultrasound skeleton mode (maximum mode) showing a coronal view of the fetal spine starting from the cervical spines to the lumbar spines and sacrum in addition to the fetal hip bone.
The assessment of the spine is essential to rule out the possibility of spina bifida and to assess the fetal bone density.
- Longitudinal plane.
- Transverse plane.
- Coronal plane.
The Skeleton mode and VCI-C of a 4D ultrasound scan shows:
1- Thoracic vertebral centra.
2- The intervertebral discs.
3- The costovertebral articulation.
4- The lung bases at the costo-phrenic angles.
5- The centra and intervertebral discs of lumbar vertebrae.
