Abstract:
Objective To assess the clinical values of MR angiography(MRA)in the detection of deep vein thrombosis of the lower limbs.Methods Two-dimensional time of flight(2D TOF)MRA was performed in thirty patients who were suspected of having deep vein thrombosis in the lower limbs.The findings of MRA were compared to that of digital subtraction angiography(DSA).Results twenty-five cases showed deep vein thrombosis in the lower limbs,the MRA findings included venous filling defect (14 cases),occlusions and interruptions of veins(8 cases),venous recanalizations(3 cases),collateral veins(25 cases).Taking the results of DSA as a golden standard,MRA detected all of the affected cases with only one case as the false positive.Conclusion 2D TOF MRA is a method of choice in the diagnosis of deep vein thrombosis of the lower limbs.
