Comparisons were made using a 4\u2010point subjective rating scale in all patients. Eighteen patients were examined with both SCTA<\/jats:styled-content> and invasive digital subtraction angiography (DSA<\/jats:styled-content>). The accuracy of SCTA<\/jats:styled-content> and routine CTA<\/jats:styled-content> reformations was assessed and compared by both patient\u2010based and vessel\u2010based analyses of intracranial aneurysms and intracranial and extracranial arterial stenotic lesions using DSA<\/jats:styled-content> results as the reference standard.<\/jats:p><\/jats:sec>Results<\/jats:title>Diagnostic accuracy in the adjacent skull base portion of the internal carotid artery (ICA<\/jats:styled-content>) and reading time for cerebral aneurysms and vessel stenoses were obviously improved with SCTA<\/jats:styled-content> protocol, but the accuracy in vertebro\u2010basilar arteries was no different.

SCTA<\/jats:styled-content> is superior to routine CTA<\/jats:styled-content> in the visualization and diagnostic accuracy of adjacent skull base part of the ICA<\/jats:styled-content> and decreases
