“…Also, for radiologists with little experience in spinal US, since they are not familiar with such rare conditions that may cause edema in the spinal cord, establishing normal and abnormal diameter values will facilitate the detection of this type of pathologies. In a recent study, Singh et al (3) reported that the mean AP spinal cord diameter was 4.1±0.5 mm at the cervical level, 3.3±0.3 mm at the thoracic level and 4.4±0.6mm at the lumbar level. The mean AP spinal canal diameter was 7.7±0.7mm at the cervical level, 6.2±0.8mmat the thoracic level, and 8.4±0.7 mm at the lumbar level.…”

Aim: We aim to reveal the normal anterior-posterior diameter of the spinal cord and canal at cervical, thoracic and lumbar levels in newborn with sonographic measurements and to create a reference value. Also, we aim to reveal whether the anterior-posterior diameter at these levels will vary with the newborn's head circumference, gender, height and weight. Thus, we aim to be one of the pioneering studies in the literature Material and Method: Statistical analysis was performed to determine normal anterior-posterior diameter for the spinal canal and spinal cord at each vertebral level, and their correlations with birth weight, length and head circumference. Results: 188 newborns were included. The mean anteroposterior spinal canal diameter in male newborns was significantly higher compared to females (9.27±0.83 vs 9.00±0.79, p=.020). There was a positive correlation between spinal cord anterior-posterior diameter and head circumference at thoracic level, which was statistically significant. There was a positive correlation between spinal canal diameter and height at thoracic level. There was a positive correlation between spinal canal diameter and weight at lumbar level. Conclusion: The establishment of the normal values for anterior-posterior diameters of the spinal cord in healthy newborns may contribute the current literature data.

“…To the best of our knowledge, the only published work on pediatric DKI (Conklin et al, 2016) is limited to grown-up children (6-16 years), whose larger anatomical structures and reduced source of movements enable better image quality and longer scan times. Indeed, in newborns, SC dimensions themselves (24 cm average length and 4.4 mm diameter, which can further decrease in case of malformations (Singh et al, 2020)), are enough to conceive amplification of aforementioned technical issues and thus justify the lack of research towards this direction.…”

Diffusion Kurtosis Imaging (DKI) has undisputed advantages over more classical diffusion Magnetic Resonance Imaging (dMRI), as witnessed by a fast-increasing number of clinical applications and software packages widely adopted in brain imaging domain. Despite its power in probing tissue microstructure compared to conventional MRI, DKI is still largely underutilized in Spinal Cord (SC) imaging because of its inherently demanding technological requirements. If state-of-the-art hardware advancements have recently allowed to make great strides in applying this emerging method to adult and child SC, the same does not apply to neonatal setting. Indeed, amplified technical issues related to SC district in this age range have made this field still unexplored. However, results arising from recent application of DKI to adult and child SC are promising enough to suggest how informative this technique would be in investigating newborns, too. Due to its extreme sensitivity to non-gaussian diffusion, DKI proves particularly suitable for detecting complex, subtle, fast microstructural changes occurring in this area at this early and critical stage of development, and not identifiable with only DTI. Given the multiplicity of congenital anomalies of the spinal canal, their crucial effect on later developmental outcome, and the close interconnection between SC region and the above brain, managing to apply such a method to neonatal cohort becomes of utmost importance. In this work, we illustrate the first semi-automated pipeline for handling with DKI data of neonatal SC, from acquisition setting to estimation of diffusion (DTI & DKI) measures, through accurate adjustment of processing algorithms customized for adult SC. Each processing step of this pipeline, built on Spinal Cord Toolbox (SCT) software, has undergone Quality Control check by supervision of an expert pediatric neuroradiologist, and the overall procedure has preliminarily been tested in a pilot clinical case study. Results of this application agree with findings achieved in a corresponding adult survey, thus confirming validity of adopted pipeline and diagnostic value of DKI in pediatrics. This novel tool hence paves the wave for extending its application also to other promising advanced dMRI models, such as Neurite Orientation Dispersion and Density Imaging (NODDI), and to a wider range of potential clinical applications concerning neonatal period.
