3. Fig 2
Sagittal T2 scan for scouting of axial scans from the level T1 to S5. Then, axial, contiguous, and 5-mm-thick T2-weighted scans were carried out from the upper margin of T1 to S5. Each scan was submitted to a circular region of interest analysis on a zoomed image (×2 or ×3).

6. Fig 5
Volume of spinal cerebrospinal fluid (CSF; in millilitres) plotted individually against weight (in kilograms) in 54 neonates. The linear regression can be described as follows: CSF (ml)=1.94 kg+0.13 (R2 =0.78). The 95% confidence intervals and prediction bandwidths are shown. Leave-one-out regression functions are given (in grey).
