Abstract

Objective To investigate the application of 16-slice helical computed tomography digital subtraction in the angiography of carotid arteries. Materials and Methods CT angiography using digital subtraction technique (Computed Tomography Digital Subtraction Angiography DS-CTA) and digital not-subtraction technique (Computed Tomography Digital Not-subtraction Angiography NS-CTA) was performed in 52 patients suspected of lesions. The findings of two techniques were compared. Results DS-CTA took less time than NS-CTA, but there was no significant difference in the image quality between both. Conclusion DS-CTA could be a kind of rapidly direct non-invasive three-dimensional angiography.
