Abstract

Objective To investigate the value of 256-multiple slice CT angiography and doppuler ultrasound in lower extremities arterial disease (LEAD). Methods 50 cases of type 2 diabetes diagnosed by DSA lower extremity arterial disease patients, underwent 256- CTA examination and DUS examination in two weeks.Analysis the imaging characteristics of the DLEAD,Each arteries with DSA as the gold standard, to calculate the sensitivity, specificity, positive predictive value, negative predictive value and the diagnosis rate of the two methods. Results 1.there was no significant difference on the overall detection rate of lower extremity arterial stenosis by 256-CTA and DUS(P>0.05). The sensitivity in observe vascular lesion under knee, using 256-CTA was better than using DUS,and the difference has statistical significance (P<0.01).2.Compared with DSA, 256-CTA in LEAD assessment, the sensitivity, specificity and diagnostic accuracy were similar. Conclusion 256-CTA method has high sensitivity and specificity in the diagnosis and evaluation of DLEAD. The application of 256-CTA is superior to DUS in Below the knee artery stenosis
