Objective:To valuate the application of 64-slice spiral CT angiography in the arterial diseases of the lower extremities.Methods:Radiography data and treatment of 27 patients with arterial diseases of the lower extremities were reviewed

the scans cover renal artery to the artery of the lower extremity.We used workstation for 3D reconstruction Results:VR and MIP findings on 64-MSCT angiography were as follows:17 abdominal aortic and lower extremity arterial mural calcification

5 pseudoaneurysm aneursm

1 hemangioma racemosum

3 thromboangiitis obliterans

1 thrombopoiesis at anastomotic stoma.Conclusion:64-MSCT angiography has high clinical potential to be used in the diagnosis of lower extremity vascular lesions

which can help screen and define the type

size of the vascular diseases

and make programme.
