Bottom Line: The results revealed that the cerebrospinal fluid peak flow velocity and peak flow rate in the systolic phase were significantly greater than those in the diastolic phase at the same level in the subarachnoid space of the cervical spinal canal.The ventral peak flow velocity and peak flow rate were significantly greater than the post-lateral peak flow velocity and flow rate, while there were no differences between left and right post-lateral subarachnoid peak velocity and flow rate.Moreover, there were no significant differences in peak flow velocity and peak flow rate between the systolic and diastolic phases, ventral, right post-lateral or left post-lateral peak flow velocity and peak flow rate at the same level in the subarachnoid space of the cervical spinal canal among different age groups (18-24, 25-34, 35-44, ≥ 45 years).

ABSTRACT
A total of 50 healthy volunteers aged between 18 and 54 years underwent phase-contrast cine MRI to assess cerebrospinal fluid flow characteristics in different regions of the vertebral canal. The results revealed that the cerebrospinal fluid peak flow velocity and peak flow rate in the systolic phase were significantly greater than those in the diastolic phase at the same level in the subarachnoid space of the cervical spinal canal. The ventral peak flow velocity and peak flow rate were significantly greater than the post-lateral peak flow velocity and flow rate, while there were no differences between left and right post-lateral subarachnoid peak velocity and flow rate. Moreover, there were no significant differences in peak flow velocity and peak flow rate between the systolic and diastolic phases, ventral, right post-lateral or left post-lateral peak flow velocity and peak flow rate at the same level in the subarachnoid space of the cervical spinal canal among different age groups (18-24, 25-34, 35-44, ≥ 45 years).

Mentions: GE Signa EXCITE 3.0T HD MR apparatus (GE, Fairfield, Connecticut, USA) was used with a spine coil. Scanning was performed while subjects lay in a supine position. We instructed participants to avoid deep breathing and swallowing during scanning. First, routine cervical spinal sagittal and horizontal axial plane scanning were performed using fast-recovery fast spin-echo scanning. The parameters were as follows: repetition time/echo time/number of excitations/flip angle, 2 400-2 500 ms/110-120 ms/4/90°; slice thickness, 3 mm; gap interval, 0.5 mm; field of view, 26 cm × 26 cm; matrix, 380 × 256. Gating was conducted and PC-MRI scanning was performed at C2-3 levels, with the location line vertical to the vertebral canal subarachnoid CSF flow (Figure 2).
