Abstract

Ten patients underwent FD‐CTA, CTA, and DSA of the cerebral arterial vasculature for suspected cerebrovascular disease. The image data were evaluated by two readers in consensus for the visualization of cerebral arterial segments on a 5‐point scale (0 = vessel cannot be distinguished; 4 = excellent image quality). The Wilcoxon signed‐rank test was used for statistical analysis. Note that <italic>P</italic> < .05 was considered to indicate a significant difference.</p> </sec> <sec id="abs1-4" sec-type="section"> <title>RESULTS</title> <p>The depiction of cerebral arterial segments with FD‐CTA was significantly superior compared to CTA in most vessel segments (<italic>P</italic> < .05 in 20 of 23 anatomic regions) and was without significant difference compared with DSA in large and medium intracranial vessels.</p> </sec> <sec id="abs1-5" sec-type="section"> <title>CONCLUSIONS</title> <p>The results suggest that the cerebral arteries can be visualized by FD‐CTA in high resolution, in many vessel segments comparable to DSA.</p> </sec> </abstract>
