Overview
MRI
MRI is more sensitive than CT to posterior circulation infarcts, particularly in the brainstem.[1] The CE-MRA(Contrast-enhanced magnetic resonance angiography)had the highest sensitivity and specificity compared against the gold standard of intra-arterial angiography. CE-MRA offers better visualisation of the extracranial vertebral system than non-contrast MRA.
