Abstract:
Objective To evaluate the application of phase-contrast (PC) cine MR imaging in monitoring the changes of cranial hemodynamics after trauma.Methods The 2D PC cine MR imaging was performed on 40 patients with cerebral trauma,admitted to our hospital from September 2010 to December 2010 and considered to have changes of cranial hcmodynamics,and 40 healthy volunteers; and the mean flow velocity,peak systolic velocity and time-averaged mean velocity of cranial segment in the jugular vein,carotid artery and vertebral artery were compared.Results The bilateral mean flow velocity in the jugular vein of patient group was significantly higher than that in the healthy volunteers (P＜0.05); and no significant differences were noted in the peak systolic velocity and time-averaged mean velocity of eranial segment in the jugular vein between the 2 groups (P＞0.05).And no obvious differences in the mean flow velocity,peak systolic velocity and time-averaged mean velocity of cranial segment in the carotid artery and vertebral artery were noted between the 2 groups (P＞0.05).Conclusion The 2D PC cine MR imaging can quantitatively monitor the changes of cranial hemodynamic after trauma in prophase,providing evidence for clinical treatment.
