Infant Spinal Canal Ultrasound

Infant Spinal Canal Ultrasound is an exam that obtains images of the infant spine with sound waves. A hand-held transducer (probe) is used to create images of the infant spinal canal. This exam can assist in diagnosing problems, such as tethered cord, spinal cyst or spinal mass.


  • The infant will lie in the prone (on the belly) position with the back exposed.
  • A non-greasy gel will be applied to the skin during the exam.
  • The radiologist or sonographer will use a hand-held transducer (probe) to create images of the infant spine and contents.


  • Typically there is no prep for this procedure.
  • Arrive 15 minutes prior to your scheduled appointment with a prescription if your doctor has given one to you.


  • Let technologist know if there is a visible sacral dimple.
  • Bring things to keep infant comfortable (i.e., bottle, blanket, pacifier).
