Learning objectives
•To know the indications of spinal ultrasound.
When to realize it?
•To describe the technique of spinal ultrasound.
•To perform the normal radio anatomy and the variants of the normal.
•To identify the elements of the report.
Background
•Spinal ultrasound is the best examination,
inexpensive,
non-irradiating screening for these spinal abnormalities mostly dysraphism
• It allows to analyze the osteocartilaginous walls of the medullary canal and its contents: spinal cord,
roots,
cerebrospinal fluid(CSF)
Anatomical reminder:
•The spinal cord is located in the vertebral canal.
•It extends from the occipital foramen to the 1st or 2nd lumbar vertebrae.
•A small fibrous filament,
derived from the meninges: terminale filum
extends from the end of the spinal cord to the coccyx.
•The spinal cord has 2...
Findings and procedure details
Technique of spinal ultrasound
•Spinal cord is easily analysable until 3rd month
•Through the posterior arches incompletely ossified.
•Infant in prone,
with pillow under the abdomen or lateral decubitus.
•Linear probe of high frequency (at least 7 MHz) with axial and longitudinal cuts from the occiput to the sacrum.
•Analysis of the bulbo-medullary junction: flexion of the neck oor phased-array that follows the physiological cervical lordosis of the infant.
Indications
Clinical lumbosacral anomaly :
Cutaneous stigma at high risk of dysraphism:
Angioma on the midline,...
Conclusion
Spinal ultrasound is the best examination in the search for spinal malformations in newborns and infants.
Normality criteria:
A conus medullaris in place,
above L3.
A filum terminale ,
equal to or less than 2 mm.
Movable lumbar and sacral roots.
Absence of echogenic mass of dural space.
Any abnormal spinal ultrasound should be
complemented by an ETF.
MRI explores the totality of the spinal cord and these envelopes in the different planes of space.
