Abstract：Objective: To evaluate diagnostic value of 16-slice spiral CT venography(MSCTV) in detecting venous thrombosis of the lower extremity. Methods: The imaging diagnosis of patients with venous thrombosis of lower extremity was performed on MSCT and processed the data on ADW4.1 workstation. The data of MSCTV were reconstructed with maximum intensity projection(MIP), multiplanar reformation(MPR), volume rendering(VR). Result: Twenty-six cases suspected of having venous thrombosis of the lower extremity were demonstrated successfully with MSCTV. It could clearly reveal the location and extension of the lesion. The pathological changes in MSCTV included swelling of lower extremity, filling defect of vascular lumen, single and/or multiple stenosis and occlusion, forming of collateralization. Conclusion: MSCTV was valuable to demonstrate venous thrombosis of the lower extremity. MSCTV was better than Doppler ultrasonography and DSA in diagnosing venous thrombosis of the lower extremity. MSCTV may be useed as the first choice technique in diagnosing venous thrombosis of the lower extremity.
