Abstract:
Objective To evaluate non-enhancement magnetic resonance venography (MRV) of iliac vein in diagnosing Cockett syndrome.Methods Magnetic resonance iliac venography was performed with Ingenia 3.0 T superconducting type MRI system.Abdominal surface coil was employed.The scanning sequences included M2DIPEAR (TR/TE=45/5.8 ms,flip angle=60°),THRIVE (TR/TE=6.8/3.5 ms,flip angle=10°),BTFESPAIR (TR/TE=3.4/1.7 ms,flip angle=80°) and FLAIR (TR/TE=9 000/120 ms,flip angle 90°).The layer thickness of 3 mm was used in all scanning,and the average number of acquisition was 3 times.Results On MRV imaging,Cockett syndrome was characterized by narrowed anteroposterior diameter and broadened transverse diameter of the compressed iliac vein,and curved impression could be seen on its anterior border,and collateral vessel formation could be observed.The mean diameters of the left iliac veins in the light,mnedium and severe patients with Cockett syndrome were 7.52,4.83 and 2.76 mm respectively,with the average compression ratios being 37％,69％ and 83％ respectively.Conclusion Non-enhanced MRV is a feasible method for the diagnosis of iliac vein stenosis,this examination is especially suitable for the checking needs of specific population.
