【Abstract】 Objective To investigate the application value of the 64-slice spiral CT angiography (CTA) tech-
nique in lower extremity arterial injury. Methods From February 2012 to April 2013 CTA examination were per-
formed in 32 cases with lower extremity arterial injury, LEONARDO workstation was used for data analysis, and pro-
cessing methods included curved MPR, volume rendering and maximum intensity projection, and then combined with
the original image, to conduct a comprehensive analysis. Results Vascular lesion extent, scope and form were good
in 32 patients, and a good outline blood vessels in CTA reconstructed image is very clear. There were 4 cases with
thromboangiitis obliterans, 2 cases with pseudoaneurysm, 5 cases with popliteal aneurysm, 21 cases with lower ex-
tremity atherosclerotic lesions. Conclusion 64-slice spiral CT angiography has great application value in the diagno-
sis of lower extremity arterial injury.
