PDFAbstract
Objective To evaluate the value of 256 slice spiral CTA in the evaluation of carotid artery stenosis and shape of carotid atherosclerotic plaque. Methods 82 cases patients with carotid artery stenosis underwent 256 slice spiral CT angiography (CTA). Digital subtraction angiography (DSA) was taken as the golden standard to understand CTA in the diagnosis of carotid stenosis and shape of plaque. Results With DSA as the golden standard, the accuracy, sensitivity and specificity of CTA in diagnosis of carotid atherosclerosis were 93.90%, 94.20% and 92.31%, respectively while those of CTA were 92.68%, 93.93% and 90.35% respectively. Except for 7 cases with occlusion, 107 carotid atherosclerotic plaques were found of which 64.49% were smooth, 25.23% irregular and 10.28% ulcer plaques. Conclusion 256 slice spiral CTA not only can accurately determine the degree of carotid stenosis, but also can reflect the shape of carotid atherosclerotic plaques, which can provide an objective basis for clinical diagnosis and treatment.
