Overview
The CT angiography(CTA) shows a high sensitivity and specificity in the diagnosis of VBI.
CT
The normal CT can diagnose subarachnoid hemorrhage following the intracranial vertebral artery dissection, but can't provide enough definition to the artery. The contrast CT (CTA) has high sensitivity (94%) and specificity (95%) to make a correct diagnosis compared against the DSA.[1] And some researchs reveal that the CT-baesd score can be used in predicting the final infarct size[2] and also for a prognostic assesment early ischemic injury in basilar artery occllusion.[2][3][4][5]
