Objective:To study the ability of 3D DCE MRA in demonstration of the invasion of the vessel by pulmonary cancer,and its value in predicting operability of pulmonary cancer.Methods:26 patients with pulmonary cancer underwent 3D DCE MRA besides conventional MRI sequences.The protocol of 3D DCE MRA was as follows: after intravenous bolus injection of 0.2ml/kg Gd DTPA,coronal 3D TFE keyhole images were obtained with 4 slices.The vessel images were reconstructed with MIP.The relationship of pulmonary cancer and the associated vessels was analyzed by correlating to surgical and pathological findings.Results:The pulmonary vessels in different phases could be demonstrated clearly with 3D DCE MRA in 25 of 26 cases.The masses adhered to the vessels in 9 cases,and surrounded or encased the vessels in the other 16 cases.Conclusion:The pulmonary vessels up to the segmental arteries and veins could be depicted clearly on the images of the 3D DCE MRA.It is useful for predicting operability of the pulmonary cancers.
