Abstract:
Objective To investigate jugular vein morphological changes with three dimension phase contrast magnetic resonance venography(3D PC MRV),and to explore hemodynamic features using MR phase contrast cine (MR PC cine).Methods Sixty-five healthy volunteers performed 3D PC MRV and MR PC-cine sannings.MRV ranged from torcular herophili to brachiocephalic veins, and the raw data of PC-cine was acquired at cervical 2-3(C2-C3)level perpendicular to the Jugular veins(JVs)with the maximum encoding velocity of 50 cm/sec.Jugular vein showing absent or tip shape(cross-sectional area less than 12.5 mm2 )was considered abnormal,and flat,crescent,oval,round shapes were considered normal.Data of PC-cine was processed by computer to evaluate the hemodynamic features.Results Nine (13.85%)of 65 cases were abnormal that unilateral jugular vein showing needle-pointed narrow or absent,and 8 cases on the left,and one case on the right;Weak correlation was found between jugular veins pattern and the age.The right sided values in volunteers were higher than that of the left side.Conclusion The morphology and hemodynamics of jugular veins in volunteers showed significant difference between sides,and weak correlation is found between the morphology and aging.
