Dual-energy X-ray absorptiometry provides two modes of head computed tomography(CT) an-giography scanning:neuro-digital subtraction angiography and dual-energy CT angiography(DE-CTA) . Previous studies have compared image quality,radiation exposure,and bone removal between neuro-digital subtraction angiography and DE-CTA. However,the number of cases was relatively small. The present study examined 300 suspected cases of cerebrovascular disease and observed the methods and duration of post-processing,examination time,and data volume. Results demonstrated similar image quality between the two methods,but lower radiation doses and shorter examination time in DE-CTA. DE-CTA allowed for faster and more stable scanning performance and post-processing methods,facilitating accurate and direct diagnosis of cerebrovascular disease.
